Abstract

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.

AAC与硅酸钙全尺寸墙体模型窗区应力-应变分析
本文介绍了带两个开窗的全尺寸墙体模型的试验结果。测试墙体由蒸压加气混凝土(AAC)单元和硅酸钙(C-S)单元组成。它们被竖立在薄的未填充的垂直接缝上。本文严格符合先前在拱肩区域进行的试验。这项研究的目的是验证在较小的模型中得到的结果。对全尺寸模型的拱肩区域进行了应力应变分析,并与小尺寸模型的结果进行了比较。通过应力应变图分析可知,拱肩区域的水平应力约为0.2 N/mm2。采用基于有限元法的软件对试验墙体进行了计算。分析了实验室测试和数值模拟的结果,以确定测试壁面的应力和应变水平。
