Mining shocks are dynamic phenomenon induced by underground and surface mining activities. In Poland, human activity generates rockbursts. They are the most intense so-called paraseismic sources. They refer to exploration of copper ore, hard and brown coal, gold, diamonds, non-ferrous metals and also originating from pile driving, driving sealed walls, and car, train, tram traffic and subway traffic. The mining-related surface vibrations can not only cause significant damage to buildings but they can also have a negative influence on people-occupied buildings. In Poland, mining tremors referring to hard coal and copper ore exploration occur at the Upper Silesian Coalfield (USC) and the Legnicko–Głogowski Copper District (LGCD), respectively. Rockbursts are not subject to human control, and they are random events concerning time, place of occurrence, and magnitude. There are many significant differences between earthquakes and mining tremors. The significant differences are magnitude, intensive phase of duration, peak ground accelerations (PGA), the range of predominant frequencies, frequency of occurrence, and depth of hypocenter. Mining-related vibrations stand out by having the highest intensity of all forms of paraseismic vibrations. It is, therefore, essential to assess the impact of this type of vibration on buildings and occupants. The study concerns impact evaluation of surface mining-related vibrations on occupants of dwelling masonry buildings using: (a) the RMS method according to British and Polish standards and (b) new version of empirical-measurement scale GSIS-2017. This scale is the base for estimating the level of vibration intensity. Intensity levels correspond to the effects of vibrations on people.

The paper discusses thermal quality improvement in historic buildings. It is based on a case study of a wooden historical building in an architectural style typical of Zakopane, located in the Podhale region of Poland. The building’s historical value and timber structure prevent the application of typical thermal retrofitting solutions. This paper presents an analysis of the possibilities of the improvement of energy performance of a historic building (villa) which included: a review of the available energy performance improvement solutions applicable to this type of building, with a particular focus on applying internal insulation; a technical condition assessment using non-invasive methods, the identification of problematic areas in terms of the thermal retrofitting of buildings with timber walls and decks; in situ tests: thermovision tests which showed the places with temperature distribution field disturbances in the building’s envelope, focusing on thermal bridges; measurements of actual thermal transmittance coefficients for extant partitions; measurements of the building’s airtightness and the microclimate in selected rooms; numerical analysis: an assessment of the influence of the thermal bridges on the building’s existing condition, an analysis of water content changes in wall systems post-insulation. The presented approach enables the improvement of the energy performance of timber historical buildings while preserving the historical value of its architecture. It is innovative because it tries to fill in a research gap concerning a lack of relevant guidelines in Poland. The research questions that the authors asked were as follows. Is it possible to improve the thermal insulation of a building’s wooden walls without adversely affecting the building’s technical condition? With regard to the necessity to meet nZEB (nearly zero energy building) standards, is it feasible to improve the timber walls of historical buildings? The study found that under the correct assumptions and while maintaining a responsible approach to design, it is possible to improve the energy performance of historical buildings without interfering with historical heritage.

Adapting historic buildings to new, modern forms generates not only financial benefits for developers but can also allow them to survive for future generations through proper remodelling. The variety of decision criteria related to the selection of a new function of a historic building makes this problem multidimensional. Many of these criteria are interrelated and have a non-linear nature which requires a comprehensive network-based rather than a classic hierarchical approach to conducting multi-criteria analysis. A comprehensive approach taking into account the specificity of the analysed problem was proposed. The study was supported by an example of the choice of building function as part of the adaptive reuse of a historic building located in Zakopane. The following variants have been analysed: a hostel (existing state), a five-star hotel, a folk art gallery and a conference and training centre. The final rating of alternatives indicates that the hotel best meets the adopted decision criteria.

The Directive 2010/31/EU on the energy performance of buildings has introduced the standard of “nearly zero-energy buildings” (NZEBs). European requirements place the obligation to reduce energy consumption on all European Union Member States, particularly in sectors with significant energy consumption indicators. Construction is one such sector, as it is responsible for around 40% of overall energy consumption. Apart from a building’s mass and its material and installation solutions, its energy consumption is also affected by its placement relative to other buildings. A proper urban layout can also lead to a reduction in project development and occupancy costs. The goal of this article is to present a method of optimising single-family house complexes that takes elements such as direct construction costs, construction site organisation, urban layout and occupancy costs into consideration in the context of sustainability. Its authors have analysed different proposals of the placement of 40 NZEBs relative to each other and have carried out a multi-criteria analysis of the complex, determining optimal solutions that are compliant with the precepts of sustainability. The results indicated that the layout composed of semi-detached houses scored the highest among the proposed layouts under the parameter weights set by the developer. This layout also scored the highest when parameter weights were uniformly distributed during a test simulation.

Mining-related seismicity is a significant problem in regions with the exploitation in underground mines. Despite the fact that mining tremors result from human activity and are classified as so-called paraseismic shocks, as with earthquakes, they are random events. Moreover, these rockbursts could cause significant damage to surface structures, including buildings. This paper deals with the analysis of experimentally obtained results in terms of the differences between the mine-induced vibrations described by the response spectra from the free-field near a given building and the simultaneously recorded vibrations in the building foundations. The influences of epicentral distance, mining tremor energy and the value of peak ground acceleration on the curves of free-field—foundation response spectra ratio were studied. The impact of the type of building on the transmission of response spectra from the free-field vibrations to the building foundations was also analysed for three types of apartment buildings (low-rise, medium-rise, high-rise). The usefulness of the approximate models of the phenomenon of soil-structure interaction during earthquakes proposed in the literature is also estimated in this paper in specific instances of mining tremors. Furthermore, the study presents original, simple, empirical models for the evaluation of the differences in the response spectra originating from free-field and building foundation vibrations in the mining region.

The idea of Sustainable Development means caring for the environment and the natural resources. Building and transport are the sectors with the highest energy consumption. Building is responsible for about 40% of total energy consumption. Thermal protection regulations for buildings are becoming more and more severe. The 2010/31 / EU Directive on the energy performance of the buildings imposes on the member states of the European Union the necessity to introduce a standard of buildings of almost a zero demand for energy (NZEB). The requirements for these buildings (NZEB) are determined for each member country of the European Union. In Poland, the requirements for buildings (NZEB) are included in the Technical Conditions. In the article, the authors present energy and cost analysis of adapting a building that meets current requirements to the requirements adopted for NZEB in Poland. The requirements for new buildings are formulated for the building envelopes and for the factor determining Primary Energy (PE). To improve thermal protection of the envelopes, for example, the insulation thickness should be increased, or windows of better coefficients should be used. To improve the PE coefficient, the amount of energy coming from Renewable Energy Sources should be increased. The improvement of thermal efficiency is associated with additional costs. The aim of the article is also to show that reducing the amount of energy necessary for heating a building is not enough to design a comfortable home. The authors pointed to the need of ensuring multi-criteria comfort in NZEB. Buildings of low energy demand are very tight and well insulated. Often, in such buildings a problem with solar energy excess appears and, consequently, the rooms are overheated. On the example of a residential building, the Authors show what costs should be covered to adapt the building to a standard that meets the requirements of the NZEB and a building comfortable for users. The analysis was carried out to improve thermal and vibrational comfort. This paper presents a fragment of research and development works carried out in under the project "Development of innovative modular construction technology, prefabricated on a wood base by Palettenwerk Kozik Sp.j." This is a new technology, developed in cooperation of PalettenWerk Kozik and Cracow University of Technology, with the support of the National Centre for Research and Development, which will have properties that significantly exceed the technology currently available on the market. Buildings made according to the developed technology with using laminated wood crosswise will be characterized by high thermal and acoustic insulation as well as high energy efficiency.

The aim of this article is to check vibrational comfort in near zero energy building (NZEB) which is often neglected for this type of building but could be annoying for residents. Building chosen for analysis is experimental building of Malopolska Laboratory of Energy Efficient Building which fulfils requirements for NZEB. The main advantage of this building is that it was design specially for research purposes and it has fourteen zones independently controlled. These zones give opportunity to ensure thermal, humidity, luminosity comfort, but do not measure vibrational comfort. Building is located in the city center of Krakow and very close to Szlak street on which cars and vans move. In this article the vibrational measurements carried out on the top floor of the building are presented. Results indicate that vibrational comfort should be taken into account in NZEB. Second part of the article describes possibility to ensure vibrational comfort in such a building by floor specially design for these purposes. In the city centres, vibro-acoustic floors could be the only solution when vibrational comfort during day or night is exceeded. Three different types of vibro-acoustic floor with different layers' configuration are described. Their advantages and disadvantages are also shown. In the end, cost analysis is made for different types of floor solutions and the most optimal solution is chosen. The selection is made not only by economic reasons but, above all, by functional premises. The floor solution chosen to be used in Malopolska Laboratory of Energy Efficient Building first of all should ensure the vibrational comfort during daytime because it is office building not residing in the night. The owners of the building will be offered an economic option that meets the requirements of vibrational comfort during the day and an exclusive option that will ensure that the vibration threshold of perception will be not exceeded.

In this article, the authors propose ways to evaluate the criteria for the considered variants of utility functions in the adaptation of historic regional architecture. The proposed set of assessment criteria (thermo-modernisation criteria, comfort of use, financial considerations, criteria of social benefits, and protection of cultural heritage) emphasises the multidimensional character of the problem of choosing a new function for a historic building. Some of the criteria are measurable while others are difficult to measure, which requires an expert approach to their assessment. The evaluation of the criteria was performed on the example of the historic building ‘Stara Polana’ located in Zakopane. The benchmark for the analysis was the existing condition of the ‘Stara Polana’ building, which is used as a hostel. The authors conducted a series of interdisciplinary studies specifying the potential of the new utility functions considered for the object in the context of the proposed criteria. The evaluation of individual criteria developed in this article is based on the multi-criteria analysis to be performed in the future and support the selection of a new function for the building in question.

In the twenty-first century, the seismic design of buildings seems to have become a fully recognised topic. There are guidelines and standards which should be taken into account by designers in seismic areas. Designers using modern international guidelines have ascertained that the behaviour of structures is not as expected. This may be the result of not taking into account the duration of the shock. The duration of surface vibrations could be one of the basic reasons why some buildings collapse or suffer severe damage to bearing systems as a result of long-duration earthquakes despite being properly designed in accordance with current understanding. Another primary reason for such collapse or damage is that some buildings in seismic areas have irregular structural systems that are sensitive to torsional vibrations. In this paper, a five-storey, irregular-shaped RC building model was subjected to different types of excitations: mining tremors, short-duration earthquakes, long-duration earthquakes. The first stage was a modal analysis based on in situ measurement. After model verification using in situ measurements, the building was then subjected to the three forms of excitation. Numerical studies were performed using a verified FEA model of the building in the time domain. The results of the calculations prove that the duration of the intensive phase of extortion is one of the reasons for the lack of building collapse in mining areas. In cases of mining shocks with a short duration of surface vibration, damage to buildings may occur which does not threaten the safety of their construction. Building collapses occur with earthquakes which are characterised by a much longer duration of the intensive phase of excitation compared to mining shocks. The results of in situ observations of RC structures that have survived a history of mining shocks of varied intensities confirm the results of numerical analyses.

Railway transport plays a significant role in shaping the quality of the environment. Vibration from railways is a big concern for engineers. Because of its negative impact on the surrounding area, it is also an environmental problem. The paper deals with the dependence of speed on the level of vibration emission. It based on the experimental study, which was done during the passage of the Pendolino train (EMU 250). Accredited Laboratory of Structural Mechanics at Cracow University of Technology has performed in situ measurements. Speed of the train was varying between 80 and 250 km/h. The evaluated construction was located at distance of approximately 50 m from the railroad. Indicators of the perceptibility of vibration through constructions (WODB) were used to access the impact of vibrations on the building. The innovation of this publication is the application of multi-criteria decision analysis methods for assessing the impact of vibration. The ELECTRE (Elimination and Choice Expressing Reality) methods to evaluate the increase in vibration emission depending on the speed for each frequency band are used. The limits specified by Polish standards in any of the passages have not been exceeded. As proven in the paper, a train speed increase does not uniformly make the vibration higher in each frequency band.

Placing emphasis exclusively on minimizing energy consumption in low-energy buildings can adversely impact thermal comfort and vibrational comfort. Vibrational comfort is extremely important in building design, especially within mining or seismically active territories, and due to car transportation in city centers. In this article, a new approach to designing passive buildings and nearly zero-energy buildings (NZEBs) in Poland is proposed, which has a strong emphasis on the necessity of providing comfort of use in passive houses and NZEBs. Additionally, vibration comfort provisions in the design process are examined. The research gap that will be addressed by the research presented in this article is to extend the comfort conditions of passive buildings and NZEBs into the area of vibratory comfort. The second goal of the project is to determine the impact of solar control systems on the conditions of thermal comfort. The conclusions from the research will allow for the optimization of design assumptions for passive houses and NZEBs. The conclusions from the tests can serve as the basis for introducing appropriate construction law requirements in Poland. The results of the research, which are presented in the article, indicate that the technical requirements that are applicable in Poland ought to include requirements regarding the use of sun blinds in NZEBs and passive buildings (not only as recommendations). In particular, the use of apertures on the south side ought to be mandated. The article can also be the basis for introducing the requirements of vibration comfort to the PN–EN 15251:2012 “Indoor environmental input parameters for design and assessment of energy performance of buildings addressing indoor air quality, thermal environment, lighting and acoustics” standard, which is the basis for designing the parameters of the internal environment for buildings.

This paper presents a selection of vibration measurement results and analyses performed with regard to their harmfulness to residential buildings. The first part of the paper refers to the analysis of railway vibrations measured in situ at the foundation level of residential building. These vibration records were then used to assess the harmfulness of vibrations relating to each train speed. Assessment of the vibration harmfulness of the building was performed with an indicator of the perceptibility of vibration through a structure (WODB), according to the Polish standard. The second part of the study refers to the creation of dynamic models of buildings with the use of the ‘Diana’ software program and analysis of their responses to railway vibrations. The thresholds specified by the standard in any of the train speeds of up to 250 km/h were not exceeded. Nevertheless, propagation of vibrations induced by train passages and their effect on the structural response of buildings is a complex phenomenon. Without in situ measurements, it is hard to assess the impact of induced vibrations on buildings. As proven in the paper, a train moving on a track at various speeds does not uniformly make the vibration greater in each frequency band.

Human perception of vibration could be the basic parameter in designing a new buildings located close to public transport. It is also one of parameter that is considered in diagnosis of building vibration. People perceived vibrations through the floor. The problem of floor vibration appear especially in old historical buildings with wooden floor when source of transport vibration change because of infrastructure development. During years road, tramway or railway infrastructure is more expanded that it was when the old buildings were built. That is why new solutions of protection against noise and vibration are needed. One of that kind solution could be vibro-acoustic floor which can reduce impact sounds and vibrations. A flooring system that insulates both acoustically and vibrantly is a common solution to reduce noise coming from impact sounds or to propagate from lower levels to higher ones and to limit the influence of vibration on people receiving vibration in buildings passively. The flooring system should therefore be capable to damp vibrations up to 100 Hz and have sound insulation of min. 25 dB. The composition of vibration insulation materials and their material parameters will be selected to optimize the acoustic and vibration protection. At the same time, the acoustic and vibration-insulating flooring system should have all the functional features that are common to the floor: ease of installation and adequate rigidity. In paper three types of vibro-acoustic floors will be considered: with full vibro-insulation, with insulation strips and with point insulation. Advantages and disadvantages of these three considered solutions will be presented. The paper is pilot study to in-situ measurement which will be held under the project of EU commission support.

The work concerns the monitoring of the technical condition of metro trains. For this purpose, a vibration monitoring system installed in buildings in the vicinity of the underground is used. Based on measured vibrations buildings, the identification of technical condition in metro trains is conducted. The results of measurements from the system are also used to assess the impact of vibrations on people staying in buildings through the WODL ratio. Exceeding the assumed levels of the WODL ratio is the basis for repairing trains by turning wheels. Statistical analysis of the data was implemented and trends for particular time periods of measurements were shown. With the entered monitoring system and the introduced WODL index thresholds, it is possible to better plan the costs associated with the repair and replacement of wheels of rolling stock, where there are large values of radial runout. According to the introduced monitoring procedure, the number of complaints from residents decreased and the comfort of their lives improved.

The paper compares the results of an approximate evaluation of mining tremors harmfulness performed on the basis of free-field and simultaneously measured building foundation vibrations. The focus is on the office building located in the Upper Silesian Basin (USB). The empirical Mining Intensity Scale GSI-GZWKW-2012 has been applied to classify the harmfulness of the rockbursts. This scale is based on the measurements of free-field vibrations but, for research purposes, it was also used in the cases of building foundation vibrations. The analysis was carried out using the set of 156 pairs ground – foundation of velocity vibration records as well as the set of 156 pairs of acceleration records induced by the same mining tremors.

This paper refers to the dynamic in situ investigation of a RC chimney and the choice of an appropriate numerical model in order to evaluate it. The first part of the study deals with the evaluation of the dynamic characteristics of a typical RC industrial chimney which belongs to a heating plant. In the investigation, different sources of excitation were used in order to better assess the structure’s free vibrations. In this investigation, wind gusts and rhythmic, human-induced swaying were used as sources of excitation in order to better assess the structure’s free vibrations. The following three pieces of measuring apparatus were used in order to record the structure’s movement: electro-dynamical strain gauges; piezoelectric accelerometers; a Doppler laser vibrometer. Power-spectral density (PSD), cross-spectral density (CSD) and fast Fourier transform (FFT) algorithms were applied to determine the natural frequencies of the structure. The second part of the study involves the determination of the calculated dynamic characteristics of the selected RC chimney. A FEM model was built and important structural factors were used in its determination. Ground properties under the foundation of the structure were applied and variations in concrete characteristics due to carbonation and decay were factored in as were geometrical imperfections of the structure. By using natural vibration excitation sources, the lowest frequency of free vibration of the structure was determined. The third part of the paper focuses on the evaluation of the accuracy of the applied models resulting in the identification of the most valuable FEM model of the chimney. Different element types and varying levels of material modelling precision were used. The results of experimental studies were used as a basis for the verification and rating of the proposed models. The most accurate model was chosen – this was defined on the basis of it being the most capable of being successfully applied in further calculations of the dynamic response of the structure.

The paper examines an influence of installation errors of the piezoelectric vibrations transducers on the output data. PCB Piezotronics piezoelectric accelerometers were used to perform calibrations by comparison. The measurements were performed with TMS 9155 Calibration Workstation version 5.4.0 at frequency in the range of 5Hz – 2000Hz. Accelerometers were fixed on the calibration station in a so-called back-to-back configuration in accordance with the applicable international standard - ISO 16063-21: Methods for the calibration of vibration and shock transducers – Part 21: Vibration calibration by comparison to a reference transducer. The first accelerometer was calibrated by suitable methods with traceability to a primary reference transducer. Each subsequent calibration was performed when changing one setting in relation to the original calibration. The alterations were related to negligence and failures in relation to the above-mentioned standards and operating guidelines – e.g. the sensor was not tightened or appropriate substance was not placed. Also, there was modified the method of connection which was in the standards requirements. Different kind of wax, light oil, grease and other assembly methods were used. The aim of the study was to verify the significance of standards requirements and to estimate of their validity. The authors also wanted to highlight the most significant calibration errors. Moreover, relation between various appropriate methods of the connection was demonstrated.

The paper deals with a selection of free-field vibration measurement results. The study is based on the vibration measurements. Vibration acceleration records and their dependence on the position of the accelerometer are shown. The study presents the results obtained in time domain and frequency domain (FFT). Nevertheless, the main aim of the paper is to compare the results of analysis which use the time – frequency domain. A Short-Term Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) are used. The use of new methods to assess the dynamic characteristics is to validate the usefulness of proposed technique for non-stationary signals.
