Abstract: Nowadays, steel construction has been widely used in structural construction. Steel has many advantages compared by the other material such as concrete or timber. Steel is more ductile and has more strength than the other material. One of the cross section which mostly used is castellated beam. Castellated beam is steel beam which has opening on its web. Some advantages of using this beam are increased the plastic moment capacity due to increasing of the beam’s depth. In structural construction, castellated beam is usually combined with reinforced concrete slab called composite castellated beam. Therefore, aims of this study are to obtain and to compare the behavior of composite castellated beam and composite solid beam in frame structure. This research conducted experimental test and finite element modelling for validation. There are two types of frame structure considered. First, frame structure with composite castellated beam for the beam element and the second frame was composite solid beam as the beam element. The result showed that composite castellated beam had a better behavior compared by composite solid beam in terms of strength which are maximum load capacity, maximum peak displacement, yield load, yield displacement, structure stiffness, ductility, maximum moment, maximum rotation and energy dissipation.
