The thermal inertia properties of construction elements have gained a great deal of importance in building design over the last few years. Many investigations have shown that this is the key factor to improve energy efficiency and obtain optimal comfort conditions in buildings. However, experimental tests are expensive and time consuming and the development of new products requires shorter analysis times. In this sense, the goal of this research is to analyze the thermal behavior of a wall made up of lightweight concrete blocks covered with layers of insulating materials in steady- and transient-state conditions. For this, numerical and experimental studies were done, taking outdoor temperature and relative humidity as a function of time into account. Furthermore, multi-criteria optimization based on the design of the experimental methodology is used to minimize errors in thermal material properties and to understand the main parameters that influence the numerical simulation of thermal inertia. Numerical Finite Element Models (FEM) will take conduction, convection and radiation phenomena in the recesses of lightweight concrete blocks into account, as well as the film conditions established in the UNE-EN ISO 6946 standard. Finally, the numerical ISO-13786 standard and the experimental results are compared in terms of wall thermal transmittance, thermal flux, and temperature evolution, as well as the dynamic thermal inertia parameters, showing a good agreement in some cases, allowing builders, architects, and engineers to develop new construction elements in a short time with the new proposed methodology.

The aim of this paper is to study and optimize the thermal performance of new lightweight and insulating composite blocks (CBlocks). These CBlocks are made up of a central expanded polystyrene (EPS) layer and two lightweight concrete layers with cavities. The aggregate of the lightweight concrete is pumice. A complete corner wall composed of six composite blocks and a specific corner block is numerically analyzed for different thermal conditions. Numerical methods were used in order to obtain the thermal behavior of these CBlocks. On the one hand, material thermal conductivity, convection and radiation inside the cavities were considered in this problem. On the other hand, the variation of the cavities was also taking into account. Finite Element Method (FEM) and Design of Experiments (DOE) have been used to study and analyze this problem. This numerical study reaches the thermal behavior of these new insulating CBlocks and provides new useful information for researchers and builders.

Current energy demand and climate target plans are leading to green energy facilities which are efficient and sustainable. Archimedean screw turbines (ASTs) are used to generate hydroelectricity in low heads. They have been manufactured and installed worldwide. However, there is a lack of knowledge about how to design them efficiently. In this study, the performance of ASTs is analyzed using an analogy between ASTs and bucket elevators. Based on this analogy, a theoretical hypothesis on how to produce efficient ASTs is proposed. The new methodology for the design of ASTs is based on two considerations: the filling level of the AST buckets must be 85% and the increase of leakage losses must be minimized. This hypothesis is numerically and experimentally studied. Two experimental prototypes were developed and installed in the north of Spain. The numerical and experimental results are provided. A discussion comparing the results of this work and other results from the literature is presented. Finally, conclusions are drawn from this work that contribute to the improvement of AST technology as a sustainable facility to generate green energy.

The thermo-hygrometric conditions to which construction materials are subjected cause their thermal performance to vary by location. These variations must be characterised in order to design building envelopes adjusted to the requirements of each situation, thus contributing to improve their energy efficiency under actual operating conditions. To this end, a functional calculation procedure that corrects the standardised thermal conductivity values of façade materials (λ-value) has been recently proposed; which considers the climatic characteristics of each location. This work proposes and validates improvements that, while preserving its functionality, overcome some limitations of the original procedure. To calculate more accurate corrections, the façade configuration and the climatic zones established by the building codes are also considered, allowing a more reliable characterisation of the design thermal transmittance of each building façade. By using climatic records gathered from 316 weather stations, a detailed isopleth map is also developed to present the applicable corrections for more than 250,000 km2 of southern Spain. The largest λ-value corrections are identified on the southeast coast and reach up to +6% in the summer months (with average annual corrections above +4%). This improved procedure can be extrapolated to any national building code that establishes constant values of thermal conductivity for façade materials and that defines thermal design requirements based on climatic zones.

Although a large number of papers have been published to date on failures in wind turbines, most of them have focused on blade failures and less attention has been paid to the tower failures. This paper analyses the causes that led to the failure of one element that finally caused the whole tower to collapse. A diagnosis of the cause of the failure was carried out after an initial on-site inspection, when the origin of the failure appeared to be in the flange that joined the tower to its base. An experimental program was carried out to analyze the characteristics of the steel in the area nearest to the flange. A non-linear simulation was then performed by the finite element method (FEM) of the flange area where the failure had occurred, including the bolts, their prestressing forces and the contact between the joined surfaces. In order to study the influence of different variables on the flange's structural response, a method based on the Design of Experiments (DOE) was used on the FEM model. Finally, the main lessons learnt from the experience are given with the aim of contributing to improving the design and construction of wind turbine towers.

The heat transfer through wood in a fire situation is controlled by several processes, such as species, rate of heating and reaction kinetics. The article examines the challenges related to the thermal analysis of Cross-Laminated Timber (CLT) beams under non-standard fire conditions using ANSYS software. In this work, three numerical simulations are developed using Finite Elements (FE). The boundary conditions applied to simulate non-standard thermal conditions are: heat flux, radiation and convection, and temperature. And these boundary conditions are useful to compare heat transfer through Cross-Laminated Timber (CLT). The thermal properties of the wood used are based on the Eurocode 5. To validate numerical models, existing experimental results are used. The results show that the heat transfer through the CLT beam could be adjusted only by conduction. Improving the adjustment with respect to radiation and convection condition.

In the research for sustainable construction, cross-laminated timber (CLT) has gained popularity and become a widely used engineered timber product. However, there are few numerical studies of the structural behaviour of CLT. Among other issues, the orthotropic properties of CLT complicate finite element analysis (FEA). This paper presents a finite element model (FEM) to predict the structural behaviour of CLT beams subjected to sustained flexural loading. This numerical model includes a material model based on the orthotropic material properties of different timber species. Furthermore, the orientation and the properties of each layer are considered. Most of the previous studies simulate CLT beams as a homogeneous material. However, in this work the CLT beam is modelled as a composite material made up of five layers with different orientations and properties. Bonded contacts are used to define the interaction between layers. In addition, nonlinearities, such as large displacement, are used to simulate the behaviour of CLT beams. The model provides the load-displacement relationship and stress concentration. Tsai-Wu failure criteria is used in the simulation to predict the failure modes of the CLT beams studied.

Background: This patent is based on the combination of caterpillar mechanisms and conveyors. Caterpillar tracks support heavy loads and adapt this support according to the ground conditions. Conveyors displace distributed loads continuously and bidirectionally using the force of friction. This paper describes a revision of previous patents related to this innovative design.\ud Objective: This paper presents an innovative patent to continuously displace heavy structures safely. The mechanism was patented in 2011 as Spanish Patent ES2367737. The combination of these mechanisms provides the design of this patent to displace heavy structures continuously and bidirectionally, while adapting to the deflection of the structures.\ud \ud Methods: The most important elements of this patent are detailed in the paper. The most innovative component is the load compensation system, which increases the safety of the displacement of heavy structures. This system controls the load applied on the mechanism, and the displacement can be stopped before the collapse of the heavy structure.\ud \ud Results: An application of the patent for launching bridges using the Incremental Launching Method is presented. This mechanism is used to displace heavy structures using the force of friction.\ud Conclusion: The patented mechanism is an original contribution for the displacement of heavy structures continuously and bidirectionally.

The aim of this paper is to understand the structural behaviour of composite slabs. These composite slabs are made of steel and different kinds of concrete. The methodology used in this paper combines experimental studies with advanced techniques of numerical simulations. In this paper, four types of concrete were used in order to study their different structural strengths in composite slabs. The materials used were three lightweight concretes, a normal concrete, and a cold conformed steel deck which has embossments to increase the adherence between concrete and steel. Furthermore, two lengths of slabs were studied to compare structural behaviours between short and long slabs. m-k experimental tests were carried out to obtain the flexural behaviour of the composite slabs. These tests provide dimensionless coefficients to compare different sizes of slabs. Nonlinear numerical simulations were performed by means of the finite element method (FEM). Four different multilinear isotropic hardening laws were used to simulate the four concretes. Coulomb friction contact was used to model the coefficient of friction between steel and concrete. Finally, a chemical bond was included to consider sliding resistance in the contact surface between steel and concrete. Experimental and numerical results are in good agreement; therefore, numerical models can be used to improve and optimize lightweight composite slabs.

An alternative modelling for flexible membranes anchored to the ground for soil slope stabilisation is presented using Smoothed-Particle Hydrodynamics to model the unstable ground mass in a soil slope, employing a dynamic solve engine. A regression model of pressure normal to the ground, qsim, and also membrane deflection, fsim, have been developed using Design of Experiment. Finally, a comparison between the pressure obtained from numerical simulation and from a limit equilibrium analysis considering infinite slope has been carried out, showing differences in the results, mainly due to the membrane stiffness.The realization of this research paper has been possible thanks to the funding of the following entities: SODERCAN (Sociedad para el Desarrollo de Cantabria), Consejería de Obras Públicas del Gobierno de Cantabria, Iberotalud S.L., Malla Talud Cantabria S.L. and Contratas Iglesias S.L.\ud The authors wish also to acknowledge the support provided by the GICONSIME Research Group of the University of Oviedo and the GITECO Research Group of the University of Cantabria.

The penetration of atmospheric water (rain) into facades creates problems for building habitability and the durability of construction materials. This study analyses the exposure of Brazilian facades to the two main climate factors responsible for this penetration: wind-driven rain and driving rain wind pressure. Daily weather records (spanning 2005–14, from 171 weather stations) were analysed. Both exposure factors were combined to assess the risk of water penetration at each site. The relationships between the different exposure indices calculated from daily, monthly and annual records were determined and compared with results from other countries. From this analysis, detailed isopleth maps are provided that allow a graphical characterization of the moisture exposure conditions of facades anywhere in Brazil. A comprehensive characterization of the water penetration exposure in Brazilian enclosures is created and can be used to establish normative design requirements for actual climatic conditions in each area of the country. In general, an increased risk of penetration was identified in the flat areas of the South and Northeast regions of the country. The sites located in the Amazon basin present comparatively lower risks, despite a greater amount of rainfall, because the wind intensity is less in these inland areas.

This paper studies the optimum way to design both type and position of the stiffeners when a steel bridge is assembled by means of the new protect-patented launching method based on a self-supporting deck system. This procedure is able to launch bridge up to a span of 150 m, in an economical and sustainable way. The main objective of this research paper is to numerically analyze the best stiffener combination and distribution along the length of bridge, both longitudinally and transversally, in order to avoid the patch-loading phenomenon in the slender webs. An optimum design of a triangular cell along the lower plate is also presented. Thus the best stiffener distribution along the deck can be achieved to solve the two most important factors during the launching of a steel bridge: the huge forces on the support section – higher than the serviceability limit state – and buckling instability due to the point loads on the bearings. In this way, a three dimensional finite element model (FEM) is built and the design of experiments technique (DOE) is applied to obtain the best stiffener configuration. The numerical simulation allows the exact definition of the response of the structure to be achieved, covering the gaps and limits which are common in some national and international codes. Very good results have been obtained, in terms of deflection, patch loading resistance and vertical load distribution on the support section. Finally, the most important conclusions of this work are given.The authors wish to acknowledge the financial support provided by the Spanish Ministry of Science and Innovation with funds from ALCANZA Research Project number IPT-380000-2010-12 and BIA-2012-31609

The aim of this paper is the development of a new hybrid methodology to study the moisture transport and heat transfer in masonry structures made up of light concrete hollow bricks (LWHBs) from the numerical and experimental points of view. In order to solve this coupled nonlinear hygrothermal analysis, an instrumented one square meter wall was subjected to eight different moisture stages in the laboratory using a special testing device during a total time of 1480 h. In order to simulate the different experimental stages, steady and transient states were implemented in the finite element models. Furthermore, the design of experiments methodology (DOE) and the goal design optimization (GDO) technique are used to calculate the best optimal parameters from the laboratory tests. Once the optimal parameters have been obtained, the finite element models for each stage are solved so that the moisture and temperature distributions were calculated. In this sense, a very good agreement between the numerical and experimental results is achieved. Finally, the most important conclusions of this study and advantages of this new methodology are exposed.
