Seismic Performance of HyFo Beam with High Depth-to-SRC Column Connections

Abstract

Seismic Performance of HyFo Beam with High Depth-to-SRC Column Connections Hybrid composite beam;Seismic performance test;Inter-story drift angle;Detail of connection; This study is a secondary study that is a cyclic seismic test of High depth hybrid composite beam and column connection after the primary bending strength test of a high depth Hybrid composite beam. Total of 3 seismic test specimens were prepared to cyclic test. The bracket and beam web spliced by high strength bolt and the bracket and beam upper flange was spliced by welding. Test results showed that the seismic strength was higher than the plastic moment($M_p$) in the positive negative moment section, the requirement of composite intermediate moment frame wes satisfied. Therefore, the requirement of intermediate moment frame can be secured by applying the details of connection of this study results.
