摘　　要：通过低周反复加载试验对3个内隔板一面贯通式节点进行了试验研究,研究了不同轴压比情况下节点的滞回性能、强度及刚度退化、延性、耗能性能及破坏特征。试验结果表明,试件的层间位移延性系数为2.11～2.32,峰值荷载时的能量耗散系数为1.141～1.502。提出了抗震设计、研究建议。A total of three experimental specimens of penetrated interior diaphragm on one side had been tested under low-cyclic reversed loading to study the hysteric behavior, strength and stiffness degradation, ductility, energy dissipation capacity and the failure modes. The only difference of all specimens was the axial compression ratio. Experimental results show that the story drift ductility ratios are 2.11～2.32, and the energy dissipation ratios are 1. 141～1. 502 at the peak load. Additional anti-seismic design and research recommendations are presented.
