The destruction of buildings walls brickwork on an unevenly deformed base

Abstract

The article is dedicated to the analysis of the results of experimental testing of brick structures resistance. The experimental testing aimed at revealing a qualitative pattern of deformation and the character of losing the bearing capacity of a system “brick beam-wall – deformed base” and obtaining quantitative data about the strained and deformed state of the system undergoing short-term force and deformation at all stages of loading. Revealing the structure and phases of deformation and destruction of brickwork subjected to the increasing loading and the construction of dependences “loading – deformation” corresponding to the process of brickwork deformation and destruction was also an important task. It has been proved that the mechanism of the destruction of brick structures walls fragments, supported by uneven deformed base, occurs according to the scheme of shear, cut and breaking to pieces, as well as destruction of brick material and mortar with clear determination of deformation stages and brickwork destruction. The results of analysis of the experiments allowed to determine the influence of the amount of loading acting on cracks formation and brickwork functioning as a whole.
