Abstract This study analyses the thermal behaviour of a new lightweight gypsum material, developed in line with the principles of the circular economy, which has reduced the thermal conductivity of these compounds by up to 30.4%. Similarly, the contribution of these compounds to the energy efficiency of LSF walls with steel structures in different configurations has been examined, including thermal break strips to mitigate the thermal bridge effect. The thermal resistance of the walls has been analysed using 2D numerical simulations, which have demonstrated the positive impact of these various solutions on improving the energy efficiency of LSF systems.
Abstract This study developed a simplified method to evaluate the fire resistance of composite slabs with steel decking protected by a novel steel shield. A numerically validated model, incorporating experimental data, demonstrated that the steel shield increases insulation failure time by approximately 25% (criterion I) and significantly reduces temperatures in critical zones. New empirical coefficients (b i c i ) were calibrated for use with the EN 1994‐1‐2 simplified method, enabling accurate prediction of the thermal and structural behaviour of this system. Mineral wool insulation provided even superior performance. The research offers a practical design tool for engineering more efficient and fire‐safe composite slabs.
Abstract An effective strategy to mitigate seismic risk and enable the use of ventilated façades in seismic regions, while taking advantage of their high energy efficiency, consists of implementing retention or containment systems that prevent the detachment and fall of façade components during a seismic event. This study presents an experimental testing program conducted on masonry infill panels constructed within a steel frame mounted on wheels, simulating ventilated brick façades. A façade containment system is evaluated with the aim of enhancing seismic safety and reducing the risks associated with the use of ventilated façades in seismic‐prone areas.
Abstract The European CONNECT4C project is focused on the development of innovative steel joints that boost the reusability of steel buildings from the design stage. These joints include demountable column splices, adaptable moment‐resisting joints, and modular pinned connections. The CONNECT4C system also features an optimized modular grid that eases the decision‐making process while allowing for remarkable flexibility. This paper showcases the CONNECT4C system using a practical application. A small demonstration building is first designed with the system's philosophy, then disassembled and, subsequently, reassembled, modifying the spans and floor heights using the same basic elements (beams, columns, and connections). The paper focuses only on geometrical adaptability, including a description of the components' capabilities that make it possible, highlighting the large level of adaptability of the system and its potential for reuse.
Abstract The paper provides an overview of state‐of‐the‐art heuristic approaches to modelling and predicting atmospheric corrosion. Focus is given to the importance of high‐quality, realtime input data for achieving accurate and reliable models. Techniques for monitoring environmental and corrosion data are described. Finally, the paper presents a new project combining a novel sensor system with a data‐driven predictive model.
