Abstract

Abstract

In order to study the influence of weak angle steel on the seismic performance of beam-column joints with reinforced webs connected with fully bloted doble-angle steel and the post-earthquake repair level of such joints, two full-scale joint specimens and one repair specimen were designed. The deformation process and failure mode of the joints were studied by quasi-static test and numerical simulation analysis with low quasi-static load applied to the beam ends. The seismic performance indexes such as hysteresis curve, stiffness degradation curve, ductility and energy dissipation were analyzed. The results showed that the failure of joint specimens was mainly concentrated in the position of Angle steel and stiffening rib. The ductility coefficient of joint specimens was 6-9, which had a high ductility level. When the thickness of angle steel increased by 4 mm, the initial stiffness and bearing capacity of the specimen were increased by 73%. The energy dissipation capacity of the repaired joint could reach 80% of the original specimen.
