摘要

A numerical analysis of complex stress state was provided on a base of compression and shear tests of wall specimens. Software package Mafem3D, which uses Finite Element Method, was applied forthis analysis. In both cases the parameters of boundary surface have been determined in accompanying laboratory tests. Results of numerical compression and shear tests were compared with findings of laboratory experiments and proved proper conformance, especially on strength under compression, deformation, cracking. The wall structure represented a typical small building. The material parameters both for structure and soil were adopted from own laboratory tests and from tests of other scientists of the Silesian University of Technology. The subsoil deformation was applied on the bottom plane of the soil solid. A horizontal strain ε and vertical radius of curvature R of ground caused changes of stresses in foundation and wall structure.
