ANALYSIS OF THE STRESS-STRAIN STATE OF MASONRY MADE OF AERATED CONCRETE BLOCKS REINFORCED WITH COMPOSITE POLYMER MESHES
Abstract and keywords
Abstract (English):
The article presents modeling cellular concrete masonry reinforced with composite meshes. Local numerical models were verified by physical experiments. Using three-dimensional models, an assessment of impact on bearing capacity of reinforcing the masonry with composite polymer meshes was made. Subject: numerical modeling of stress-strain state for buildings made of cellular concrete masonry. Materials and methods: the research was carried out on numerical models in the LIRA-SAPR software using the finite element method in a physically nonlinear formulation Results: using local models, nonlinear characteristics were determined that allow reliable modeling of cellular concrete masonry. Then, using three-dimensional models, an assessment was made of the effect of the usefulness, type and degree of reinforcement of cellular concrete masonry with composite polymer meshes. Conclusions: cellular concrete masonry is a material that allows for an energy-efficient building. Reinforcement of masonry using composite polymer meshes allows to significantly increase the seismic resistance of the building's load-bearing system.
