Abstract

The increasing demand of material, especially steel, inspired the experts in Europe and America to create innovation steel beam which provide high strength but require less material on the making, which we known as castellated beam. Castellated beam actually was an original IWF beam which is cut by several pattern and welded properly in different part to provide higher profile. Castellated beam also provide higher inertia moment which increasing the strength of the beam. There are also several factors that impact the strength of castellated beam such as, opening angle, cutting width, profile length, etc. This analysis aims to determine the relationship between profile lengths of castellated beam with the strength that the profile could bear until it fully failed, also observing buckling and failure behaviour on castellated beam using finite element method. This issue is necessary due to the characteristic of steel which easily get buckled. Buckling that occurred isn’t instantly make steel fully lost its strength, the plastic condition will be reached first as soon as the steel lost its strength completely. This analysis will be assisted by modelling the castellated beam profile using finite element based program. The profile size is IWF 200x100x5.5x8 which is formed into castellated beam size 300x100x5.5x8 with various lengths such as 4 m, 6 m, 8 m, 10 m, and 12 m. The load applied was concentrated load in the middle of the span, with fixed support on both edges of the beam. The results show that the shorter beam profile provides higher strength, and an extreme buckling phenomenon occurs to the longer beam profile, also the longer beam profile fails due to pre-yielding condition, therefore the failure is caused by geometric fails.
