Abstract

Utilisation of Castellated beams has turned out to be exceptionally prominent nowadays because of its favourable structural applications. Steel beams having openings in the web portion is called as Castellated beams. The openings mostly made in the webs are hexagonal, diamond, circular or square in shape. One consequence of existence of web openings is the reduction of flexural and shear strength due to the development of various local effects. It also leads to a considerable decrease in the load carrying capacity of the beam. Therefore, the shape, size and location of the openings provided on the web are always an important issue of concern considering the structural performance of the beam. In this work a comparative analysis of steel beams having different cross section has been done in which different loading and support conditions are considered. This work examines the effect of circular opening with different opening size on steel beams. The maximum stress and deflection pattern are studied analytically. For this study ANSYS software have been used. Analysis showed that the steel beams have no significant effect on deflection due to the opening near the support. The Von Mises stress and shear stresses increase as the size of opening increases.
