摘　　要：T型钢梁柱节点是典型的半刚性连接形式之一,目前已初步应用在工程实践中。本文对T型钢连接原型模型进行循环荷载作用下的试验研究,并对试验模型进行非线性有限元分析计算,分析了剖分T型钢梁柱连接节点在循环荷载作用下的破坏机理,为T型钢梁柱连接在钢框架中的应用提供一定的理论依据。Slit T steel connection is a typical one of the semi-rigid connections,which has found a preliminary application in engineering practice.In this paper,the hysteretic behavior of the slit T steel beam-column connections under cyclic loading is presented experimentally,and also full-scale model of the slit T steel connections was analyzed using ANSYS.The failure mechanism of the slit T steel beam-column connections is analyzed entirely.At last,some theoretical basis is suggested for applying the slit T steel connections in steel frame.
