Experimental test for the seismic performance of PCS structural system

The PCS system, which consists of precast concrete column and steel beam, is a kind of composite structural systems. In this paper, experimental study has been conducted to analyze seismic performance of bolted beam-to-column connections for the PCS system. Based on experimental results from the seismic testing of eight interior PCS specimens, it shows that the PCS system is satisfied with seismic performance criteria of ACI such as strength deterioration, stiffness degradation and energy dissipation capacity. All of the specimens maintain their strength at large levels of story drift without significant loss of stiffness and show ductility of high level for inelastic behavior. The energy dissipation capacity is two times more than requirement of ACI criterion.
