Finite Element Approach for the Bending analysis of Castellated Steel Beams with Various Web openings

Öz

The use of perforated steel beams (PSBs) has become of great importance due to their wide application in building construction and their beneficial uses as they are economical in terms of cost in addition to their lightweight. The aim of this study is to investigate the static behavior of castellated beams with different web openings. A 3D finite element analysis is performed based using ABAQUS, to find out which type of beam gives the best performance under the same distributed load and fixed support condition. Different shapes are used for the web openings and compared with the basic shape of the hexagon, taking the same area into consideration for all shapes. In this paper, a new design model is developed using more than one shape in the web opening. Displacement and stress results are carried out and compared for various cases.
