Abstract

Because of non-ductile nature of buckling mode of failure, web-post failure examination of castellated steel beams is considered a critical issue in designing. A detailed numerical study is performed on the shear response of castellated steel beams, susceptible to web-post buckling in this article. The accuracy of the previously proposed formulation is evaluated for the mild steel models and it is found that the available methods fail to accurately predict the web-post buckling load for these beams. A considerable number of finite element (FE) models of mild steel castellated beams, are analyzed and added to the previously developed data bank. Based on these data, consisting of 300 models, a modified formulation is proposed to estimate the critical buckling load of castellated beams, considering material type. A case study analysis of a damaged castellated beam revealed some important factors for a safer design of these beams.
