ANALYSIS OF THE STRESS-STRAIN STATE OF MASONRY MADE OF AERATED CONCRETE BLOCKS REINFORCED WITH COMPOSITE POLYMER MESHES

Abstract

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.
