摘　　要：通过拟静力试验,分别对节点核心区无箍筋、柱内核心区有钢筋网片和柱内有小型钢柱三种不同构造的混凝土柱-钢梁边节点的破坏特征、破坏机理以及抗震性能等进行了研究。研究结果表明:设置小型钢柱并在节点核心区内配置箍筋的节点具有较高的承载力和良好的耗能性能;节点配箍率对其极限荷载影响不大,但能影响试件在达到极限荷载后的延性。Through the quasi-static test, the failure characteristic, failure mechanism and bearing performance of three different structure side joints of concrete column and steel beam are studied. The joint, in which the formed steel column and the stirrups are set, has higher bearing performance and better energy dissipation capability. There is less influence of the quantity of stirrups on the ultimate load, but it can affect the ductility of the joint after the load reaches the ultimate load.
