| 摘 要： | 将削弱式连接与方钢管混凝土柱-钢梁节点结合起来研究,对其进行了非线性有限元分析,得到了在往复荷载作用下削弱式连接节点的应力发展状况、应力分布以及结构塑性铰出现的顺序,并简单介绍了削弱式连接对节点性能的影响。分析表明:削弱式连接的构造形式对节点能起到保险丝的作用。

| Abstract: | Integrating weakened connections into concrete-filled square steel tubular column and steel beam joints,it is conducted a nonlinear finite element analysis.It is got that the conditions of stress development and the distribution of stress of this connection.In addition,the appearing orders of plastic hinges in this frame under cyclic load are analyzed.At last,the effects of weakened rigid connections on mixed constructions are simply discussed.Analyses show that weakened beam-column connections can be a fuse of joints in mixed constructions. |
