CAD analysis for stress and strain behaviour of masonries made of hollow ceramic blocks

[摘要] Nowadays, one of principal directions to increase energy performance of both existing buildings and those under construction is application of thermal efficient enclosing structures. Therefore, hollow multislot ceramics is very promising material to be applied in exterior walls due to predicted properties thereof and operational reliability. The results of stress analysis and strain behavior of load-bearing wall structures are presented here in, and simulation and strength properties calculation of hollow ceramic blocks are made through SCAD software thereby making geometry parameters for the fracture models. Behavior of Bashkortostan-made hollow ceramic blocks under pressure is found under experimental research of masonries, with the expected fracture process being proposed. Modern software systems are demonstrated to be likely applied for analysis of stress and strain behavior of masonry constructions made of both traditional wall materials and hollow ceramic blocks. Comparative analysis of calculation results is made using PC and "manually", with residential high-rise buildings and walls of different thickness taken as an example. Application of hollow wall items in load-bearing exterior and interior walls was confirmed both for high-rise and low-rise construction.
