摘　　要：该文提出一种工字型钢梁与钢管混凝土束剪力墙端板式刚接节点。采用塑性极限分析方法,推导出端板厚度设计方法。通过6个试件的低周反复荷载节点试验,验证了该节点力学性能和计算结果的可靠性。通过实际工程示范,验证了该节点的制作、运输和施工便利性。结果表明:该设计方法能够满足工程应用要求,安全可靠。A rigid end-plate joint of I-shaped steel beam-to-shear wall formed by concrete-filled multicellular steel tubes(CF-MCST)was proposed.The design method of the end plate thickness was deduced by the plastic limit analysis method.The reliability of the mechanical properties was verified by the calculation results of 6 specimens under low cyclic repeated loading.The convenience of fabrication,transportation and construction of the joint were verified by a practical engineering demonstration.The results show that the design method can meet the requirements of engineering applications and is safe and reliable.
