“…Thus, the objective of this article is to verify the feasibility of using a numerical model, using commercial software based on the finite element method (FEM), to study the behaviour of the facade subjected to the effect of thermal shock, by comparing the results obtained in the simulation to the values obtained from superficial temperature changes and horizontal deflections in a concrete wall instrumented and tested in the laboratory. The results show the importance of using computer simulation as an auxiliary tool for studying the durability of facade, mostly to new building systems, used in social housing (Martins, 2021;Ornellas, 2021).…”

The aim of the paper is to analyse the performance of a precast concrete wall system under heat and thermal shock (physical phenomena). The understanding of thermal shocks in building systems is a challenge because of the requirements and complexities of the phenomena behaviour through cycles of heating and cooling provided by the environment (sun followed by suddenly rain). The period of duration of the phenomenal during the cycles makes changes in the systems responses in terms of mechanical and physical aspects. The responses of the building system to heat and thermal shock were analysed during the monitoring of the changes in temperature and deformation using sensors in a scalable prototype of a precast concrete wall system. In addition, a numerical simulation based on the finite element method (FEM) in commercial software was conducted to verify and analyse the variables in a digital model of the wall as a complementary study of the effects of heat and thermal shock. The results demonstrated the feasibility to use numerical simulation to analyses the phenomenal of heat and thermal shock on the behaviour of a precast concrete wall system.
