Stress Distribution In a Shear Wall – Frame StructureUsing Unstructured – Refined Finite Element Mesh

Abstract

A semi-automatic algorithm for finite element analysis is presented to obtain the stress and strain distribution in shear wall-frame structures. In the study, a constant strain triangle with six degrees of freedom and mesh refinement - coarsening algorithms were used in Matlab® environment. Initially the proposed algorithm generates a coarse mesh automatically for the whole domain and the user refines this finite element mesh at required regions. These regions are mostly the regions  of geometric discontinuities. Deformation, normal and shear stresses are presented for an illustrative example. Consistent displacement and stress results have been obtained from comparisons with widely used engineering software.
