Abstract:In order to set up the restoring force model of connection in innovative hybrid coupled wall system, three fullscale connections in innovative hybrid coupled wall system with shearyield typed coupling beams were tested under low cyclic loading. The main test parameters were spantodepth ratios and setting parameter  of surface bearing plate. The hysteretic loops, skeleton curves, the law of strength deterioration and the law of stiffness deterioration of connection in innovative hybrid coupled wall under low cyclic loading were obtained. The experimental results show that the new connection shows well seismic performance, and the performance of the connection is similar to the link in the eccentrically braced steel frame. Based on the experimental data, the  restoring force model of the connection was built through regression analysis method. Comparison analysis shows that the model calculating results and experimental results agree well.

Keywords:hybrid coupled wall; seismic performance; restoring force model; strength deterioration; stiffness deterioration
