CAD simulation for stress and strain behaviour of wall constructions made of hollow ceramic blocks

Abstract

Research results for analysing stress and strain behaviour of wall constructions made of hollow ceramic blocks are presented herein. FEM simulation for masonry construction is given. Application of CAD methods for masonry calculation as opposed to traditional ones enables us to evaluate more clearly the entire real stress and strain behaviour not of several partitions but of the building itself on the whole, to figure out stress redistribution and the most loaded areas which is of greater importance under loading intensification and using of new cavity walls. Application of current software packages is theoretically proved when analysing stress and strain behaviour of masonry constructions made not only of traditional wall materials but of hollow ceramic blocks. Comparative analysis between computer calculation and traditional “manual” calculation has been made taking residential varied-height buildings with different wall thickness as examples. The calculations have proved that hollow wall blocks manufactured by domestic enterprises may be applied in load bearing walls both inside and outside of low-rise and high-rise buildings (9-12 storeys).
