Abstract

Abstract

A double angle steel-shear web joint frame suitable for high intensity area was proposed. A multi-story prefabricated steel structure housing in Xuzhou was selected as the design and test prototype. The seismic performance of the double angle-steel shear webs joint frame and the original joint frame model were studied under quasi-static. The damage of the two frame specimens first appeared on the external wall panels, and then on the angle steel stiffeners at the beam-column joints and the column roots. The results showed that the bearing capacity of the double angle-steel shear web joint frame was slightly lower than that of the original joint frame, but the yield displacement of the double angle-steel shear web joint frame was larger. The hysteresis loop at the early stage was slightly thinner. In the later stage of loading, due to the shear web and avoidances angle formed three supporting points toward constraint hysteresis loop more full. The ductility of the two frames could meet the design requirements. The energy dissipation capacity of the double-angle steel-shear web joint frame was slightly lower than that of the original joint frame but had a large space to rise in the process of late failure, which could meet the requirements of seismic area for structural design.
