摘　　要：本文对部分包裹混凝土柱与型钢梁外伸端板连接节点的抗震性能进行了试验研究。共设计了4个构造不同的梁柱节点,通过施加低周反复水平荷载,研究该节点各连接组件板域的应变分布及破坏模式,分析端板厚度、加劲板、背垫板对节点承载力、刚度、延性及耗能性能的影响。The seismic behavior of partially encased concrete columns and steel beam connection was tested. Four different beam- column connections are designed. The strain distribution and failure modes of each connected component domain are researched by applying a low cycle repeated loading. The influence of the thickness of the end plate, stiffeners, backing plate on the node bearing capacity, stiffness, ductility and energy consumption performance are analyzed.
