Abstract:
The force performance tests of 6 specimens of concrete-filled rectangular steel tube(CFRST)K-joints and 1 specimen of hollow rectangular steel tube(HRST)K-joints were carried out, compared with Packer’s experimental results, the failure mode of CFRST K-joints and influences on joints performance of joint gap were analyzed contrasting with HRST joints results. The method to differentiate K-joint or Y-joint of CFRST was provided. The experimental results show that yield-line failure mode of CFRST K-joints is not found, and the ultimate bearing capacity of CFRST joints are improved. Like the HRST joints, the failure mode of tension branch is punching failure mode or the effective width failure mode. If the bearing capacity of compressive branch is enough, the failure mode of compressive branch is local transverse compression failure mode of chord. When the ratio of width and thickness of CFRST K-joints is large, the influences of joint gap for bearing capacity can be ignored, while the ratio of width and thickness is small and joint gap is large, the influences of joint gap on K-joints ultimate bearing capacity should be considered.
