This paper is aimed at investigating the usage of flexible joints in masonry infilled walls surrounded by reinforced concrete (RC) frames. For this purpose, a real-size specimen was numerically created and exposed to the seismic loads. In order to evaluate both in-plane and out-of-plane performances of the infill walls, the system was chosen as a box shaped three-dimensional structure. In total, three different one-story constructions, which have single bays in two perpendicular directions, were modeled. The first type is the bare-frame without the infill walls, which was determined as a reference system. The second and third types of buildings are conventional mortar joint and PolyUrethane Flexible Joint (PUFJ) implemented ones, respectively. The influence of these joints on the material level are investigated in detail. Furthermore, general building dynamic characteristics were extracted by means of acceleration and displacement results as well as frequency domain mode shapes. Analyses revealed that PUFJ implementation on such buildings has promising outcomes and helps to sustain structural stability against the detrimental effects of earthquakes.

This paper presents the issues of assessing the comfort of people staying indoors who are exposed to vibrations and material noise caused by vibrations of partitions like floors and walls (ground-borne noise). Current criteria in the evaluation of vibrational and acoustic comfort cannot be assessed in the context of the simultaneous occurrence of stimuli such as noise and vibration. Railway transport, including passenger and cargo transport, is becoming increasingly prevalent, and new railway lines are being planned for environmental reasons. Sometimes, there are changes in stimuli produced by existing railway lines. For example, high-speed trains appear on an old railway track. Such a situation appeared on the Central Railway Line in Poland, which is still used by old trains, yet its operator plans to raise their speed limits. The analysis of the problem of the simultaneous occurrence of stimuli presented in this paper was based on measurements performed in a residential building located near the Central Railway Main Line in the city Zawiercie. Noise and vibration as the analyzed stimuli in both cases meet comfort requirements, yet when exposure to two stimuli was considered, comfort may be at risk.

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 duration of vibration taken to the analysis influence on the result of evaluation of human perception of vibration. In this paper the relationship between the duration of individual events and the result of RMS and VDV analysis was investigated. The analysis was carried out on two buildings located close to Warsaw Metro line 1. The chosen buildings are typical masonry buildings located in the city center and subjected to three sources of traffic vibrations: subway, tramway and road. Evaluation of human perception of vibration was made using two different methods, the most popular, root mean squared method (RMS) and vibration dose value method (VDV). Methodology of these two methods is also described in the paper. The results from RMS and VDV methods are compared by using HPVR (human perception of vibration ratio) for RMS analysis. It is ratio discovered by prof. Stypula and it is very useful for the diagnosis. The conclusion from analysis are given.

Transport vibrations are transmitted from the ground the foundations and building walls to the building and received by its construction and by people in the buildings. During the vibration of buildings, inertia forces generate an additional (apart from the static one) loading of the structure. In the diagnosis and design of buildings, these forces are taken into account by analyzing the requirements for stiffness and strength of the building structure. Exceedance of these requirements may lead to accelerated wear and even structural damages of the building. In this paper a simple relationship between ground and building vibration was made. The building chosen for analysis is light-weight wooden building located close to Cracow near Zakopianka road. What is worth noting that building is so called passive building. The excitation which was simulated on the dynamical polygon was car (bus) and truck lorry passages. The sensors were accelerations in three orthogonal directions, one sensor was placed about 2.5 m far from the building and the second on the foundation wall. The different types of excitation were compared and the conclusion from the analysis was made.

Human perception of vibration is very subjective parameter which depends among others on age, sex or even nationality. There are three main methods of assessment of human perception of vibration according to national standards which differ from each other. All three methods are clearly described in this paper and their advantages and disadvantages are shown. Evaluation methods are helpful in diagnosis and design of the building when they are used properly. One of interesting aspect of quality of measurements is localization of measurement points. The choice of localization of measurement points could have significant influence on result of evaluation of human response to vibration. International and national standards are compatible in this matter – measurement points should be localized in the place of human vibration perception. It means that should be located in the middle of the floor. Sometimes it is difficult to determine the exact center of the floor, especially when building has irregular construction. In this paper influence of localization of measurement point on human perception of vibration is investigated and center zone in which measurement results are proper is determined. In-situ measurements were made to investigate the problem of localization of human vibration perception in buildings.

Vibrations propagating through the soil into the building can not only be harmful to the building structure or cause its accelerated wear, but can also effect on the vibrational comfort in the rooms. They can also be annoying for residents and building users, and in extreme cases can lead to sleep disorders, headaches and neurotic conditions. Especially vibrations from the low frequency range from 5 to 25 Hz are undesirable, because there are resonance frequencies of human internal organs in this frequency range. The human perception of vibrations in buildings, despite many researches made in the past, despite standards and requirements in this area, is still a topic not fully understood mainly due to the subjective nature of the perception of vibrations by various people. It is widely known that the type of transport vibration source has an impact on human perception. Vibrations generated by above-ground sources are more felt on the upper floors as opposed to vibrations generated from the underground. In this paper three types of transport vibrations are analyzed on one chosen building located in Warsaw. Human perception of vibration is evaluated according to two methods: root mean squared (RMS) and vibration dose value (VDV).

The aim of this article is to check comfort in the passive buildings located in Libertow (close to Cracow). The two aspects of comfort are described: a thermal comfort with tightness and humidity and a vibrational comfort. The main results of measurements of the comfort aspects are described and shown. Passive buildings which were investigated are very tight and well insulated. It is good for the energy saving and for the budget of the owners but it could be a problem for the humidity requirements. In such buildings, there also could be a problem with solar energy excess which could provide that the rooms are overheated. The vibrational aspect is also often neglected on the design stage, but it also could be a problem when the residents live in their homes. The problem is that when a house is built, the costs of changes to adapt the rooms to the appropriate comfort level are much higher than in the design stage. The alternative may be a properly designed floor which shall meet all thermal and vibrational aspects of comfort. In order to improve the quality of multi-faceted comfort, three types of flooring have been proposed. All three are clearly described and their advantages and disadvantages are shown. The main goal of this article is a detailed cost analysis of these three types of floor. Cost analysis was made according to the Polish requirements so-called Catalogs of Material Inputs in the NormaPRO. Costs were estimated using detailed, simplified and mixed methods. The most effective and economically justified type of floor was also chosen.

The article contains guidelines related to the proper performance and analysis of the measurements of human perception of the vibration in buildings. The recommendations apply to both hardware requirements and the selection of measurement points as well as the analysis of the recorded signal. The buildings located in the so-called dynamic impact zone are the subjects of the analysis of the influence of vibrations on people in the buildings. In this article, the range of dynamic impact zones from different dynamic excitation is listed. An extremely important aspect of the measurements of the human perception of the vibrations in buildings is the selection of the location of measurement points. In different national standards, there are different guidelines which are compared in the article. The most proper locations are investigated. A separate issue is the selection of the measuring range and the selection of corrective filters for the analysis. New trends in this matter are shown and requirements according to the different standards are compared. A separate problem is determining the duration time of vibrations, which should be taken into analysis. It is worth noticing that the choice of duration can have a significant influence on all the results of the analysis of human perception of the vibration in buildings and many standards do not give any recommendations in this subject. The last problem of the methodology of measurements of human perception of the vibrations associated with the analysis of the measurement data is the sampling frequency of the recorded signal. The so-called N-qyst frequency has been shown in the paper and explained in a specific example...

The article contains good practise recommendations related to the proper performance of measurements of comfort in passive buildings. Passive building is a high-quality building due to impeccable construction in terms of building physics. The passive building is so well insulated that it can only be heated by supplying fresh ventilation air. Such buildings have certain features such as: balanced temperatures, there is no overheating of the rooms in summer due to the high insulation of the partitions, high insolation due to the optimal positioning of the windows, acoustic comfort, reducing pollution in the interior, high quality of thermal comfort, no aeration, high indoor air quality, permanent protection against moisture and fungiculation of partitions, etc. In all the features listed above, there was no vibration comfort, which could be a problem especially in the city centers with extensive transport infrastructure. This kind of comfort is mostly neglected during the design process, not only in the passive buildings. In this article comfort in passive buildings for all its aspects is described. The main emphasis in the article was put on the guidelines relating to the measurement of thermal comfort and measurements of vibration comfort. The recommendations contain all stages of the measurement process from the preparation of measurements with the local vision and the measurement plan, through the in-situ measurement to pre-processing and analysis of measurement data. All measurement stages are shown on the real example of passive building located in Poland. The good practise guidelines for comfort measurements could be very useful in the diagnosis of passive buildings and NZEB buildings.

Transport vibrations are the subject of many research, mostly their influence on structural elements of the building is investigated. However, nowadays, especially in the centres of large cities were apartments, residential buildings are much closer to the transport vibration sources, an increasing attention is given to providing vibrational comfort to humans in buildings. People who buy apartments in the tourist attractively cities like Cracow expect to be very close to the downtown and at the same time to have quiet place to rest without any annoyance coming from transport vibration. Unfortunately, tourist attractively cities are mostly old cities with old buildings which were not designed for dynamic influences which are now in the neighbourhood. At the same time, old buildings are under the conservator care, who limits the possibility of using some solutions. There are three types of possible protection against vibrations: vibroinsulation in the source of vibration, vibroinsulation on the way of propagation and solutions in the building. The first solution depends on goodwill of infrastructure owner, the second could be complicated in the city centres and the third is the best for apartment owners but it could be expensive. The paper presents three different types of vibro-acoustic floor with different layers' configuration. Their advantages and disadvantages are also shown. In the article the main emphasis was put on the technology of making these three types of floors in terms of the possibility of their assembly in a historic building. Detailed technological parameters have been described. The paper also proposes vibroacoustic materials that can be used as a floor layer which could isolate from transport vibrations

Nowadays, in the increasingly expanding of dynamical influences in the more and more urbanized cities and increased awareness of the owners of the buildings vibrations could be a problem. This paper considers the problem of an inventory of buildings damages as collateral for the investor as well as for owners of buildings located in the zone of dynamical influences. The “0” state inventory could be very helpful base. In this article good practice guidelines during such inventory are clearly described.

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.

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.

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.

At the workplace of the machine operator, low frequency whole body and hand- arm vibrations are observed. They occur together with noise. Whole body vibration in the range of 3-25 Hz are detrimental to the human body due to the location of the resonant frequency of large organs of the human body in this range. It can be assumed that for this reason people working every day in such conditions can have reduced working efficiency. The influence of low frequency vibration and noise on the human body leads to both physiological and functional changes. The result of the impact of noise and vibration stimuli depends largely on the specific characteristics of the objects, which include among other personality traits, temperament and emotional factor. The pilot study conducted in the laboratory was attended by 30 young men. The aim of the study was to look for correlations between the need for stimulation of the objects and their psychomotor efficiency in case of vibration exposure and vibration together with noise exposure in variable conditions task. The need for stimulation of the objects as defined in the study is based on theoretical assumptions of one dimensional model of temperament developed by Marvin Zuckerman. This theory defines the need for stimulation as the search for different, new, complex and intense sensations, as well as the willingness to take risks. The aim of research was to verify if from four factors such as: the search for adventure and horror, sensation seeking, disinhibition and susceptibility to boredom, we can choose the ones that in conjunction with varying operating conditions, may significantly determine the efficiency of the task situation. The objects performed the test evaluation of their motor skills which consisted in keeping the cursor controlled by a joystick through the path. The number of exceeds of the cursor beyond the path and its maximum deviation was recorded. The collected data were used to determine the correlation between the working efficiency and the need for stimulation of the objects under the influence of vibroacoustic factors. The analysis of the results allowed to define a set of criteria that make up the arduous working conditions. The obtained results indicate the need for the continuation of the research.
