Structural Analysis of Castellated Beam

Abstract

Castellated Beam is also called as perforated web. Main objective of perforated web is to increase the depth of section so that the moment of inertia parameter will be increase. Castellated beam have been used in many year. The castellated beam were firstly used in Europe in 1950s due cheap labor cost. Castellated beam is a name commonly used for type of expanded beam. The primary advantages of castellated beam is the improved strength due to increased depth of the section without any additional weight. This new type of beam showed a mechanical behavior similar to that of isolated rectangular openings mainly regarding the Vierendeel bending. In castellated beam to avoid local failure of beam provision of plate below concentrated load.
