An investigation on the seismic behavior of castellated beams under explosion loads effect
Due to the widespread use of ceilings with T-shaped beams as well as because of economic problems and the lack of sufficient variation of rolled profiles, applying castellated beams in buildings with steel structure has become quite common. Therefore, the present study aims to investigate the behavior of castellated beams with rigid and semi-rigid connection and surrounding in and non-surrounding in concrete under blast effect. The same pattern was modeled in Abaqus software and the cyclic load was introduced in the form of a domain to the software. The results showed better performance of the beam in rigid connection compared with semi-rigid connection against explosion. Moreover, binge surrounded in concrete causes the castellated beams to perform much better than non-buried mode and improves various drawbacks of the castellated beams. Castellated beams failure mode in the cyclic load is at the same time failure mode (local lodge of lower wing in front of the first opening after the connection) that this deficiency is largely eliminated by adding a reinforcement plate wing.
