Abstract

To study the seismic performance of the frame underpinning joints, 5 wrap-underpinning joints under frame column were designed and constructed. The cyclic loading tests were conducted and the influence on the failure mode and seismic performance of the height of interface and interface reinforcements were studied. Finite element mode of underpinning joint was established, and the accuracy of the model was verified by comparing the simulation results with the test results. The test results and analysis results show that the seismic performance was influenced most significantly by the interface height. When the joint height is 200mm, the interface reinforcement affects the failure mode of the underpinning joint, and the initial stiffness of the underpinning joints increases with the increase of the interface reinforcement. when the height joint is 300mm, the interface reinforcement has little influence on the seismic performance of the frame underpinning joints.
