Behaviour of Optimized Honey Comb Beam Under Monotonic Loading

Abstract

Honey comb beam is a steel beam which has opening on its web. The advantage of this beam is to increase the bending capacity of the beam due to increasing of inertia moment and plastic moment of steel beam section. There are three important variables which determining the capacity of the honey comb beam, i.e. opening space, opening angle, and opening ratio of the honey comb beam. This paper presents the behavior of honey comb beam which has firstly been optimized and has been done by using fast multi swarm optimization (FMSO). In the previous research, there are two cases of optimization considered. First case is optimization of opening space and opening angle with certain opening ratio, while the second case is optimization of opening space, opening angle, and opening ratio. Based on FMSO, the result showed that the second case of optimization has a better result than first case of optimization. Therefore, in order to validate the result of FMSO, the finite element analysis was conducted to obtain the behavior of optimized section of honey comb beam using monotonic loading.
