Stress-strain analysis in the window zone area of full-scale wall models made of AAC and calcium silicate units

This article presents results of tests on full-scale wall models with two window openings. Tested walls were made of autoclaved aerated concrete (AAC) units and calcium-silicate (C-S) units. They were erected on thin unfilled perpend joints. This article strictly corresponds to previous tests performed in the spandrel area. The aim of the research was to verify results obtained for smaller models. Stress-strain analysis of the spandrel area in full-scale models was performed and results were compared with results obtained for smaller models. According to the analysis of the stress-strain graphs, it was found that the horizontal stress in the spandrel area was ca. 0.2 N/mm². The software based on the finite element method was used to perform calculations for tested walls. Results from laboratory tests and numerical simulations were analyzed to determine the level of stress and strain in tested walls.
