Abstract

Abstract

In order to study the effects of opening shape, opening ratio and concrete floor on the seismic performance of the end-plate joint of castellated beam-to-column, four full-scale side joints were designed and tested under quasi-static loading. The failure mode, bearing capacity, ductility and energy dissipation of the specimens were studied. The results showed that for the specimens with floor plates, the opening shape had a great influence on the failure mode and seismic performance of joints, the hexagonal opening was more prone to beam hinge failure and showed a better energy dissipation. The opening ratio had a great influence on the failure mode, bearing capacity and ductility of the joints, appropriately increasing the opening ratio was conducive to the stress migrated from the end plate connection to the first opening, and the strain limit value between the end plate and the column flange was reduced. The combined effect of the floor increased the flexural capacity of the joints by more than 25%, the energy consumption and ductility by 16.5% and 30.7%, and the ultimate angle by 40.9%, respectively, but weakened the stress migration effect from the end plate joint to the first opening.
