摘　　要：对采用带腹板双角钢的顶底角钢连接(简称四角钢连接)的半刚性钢梁柱连接节点进行精细的三维非线性有限元分析。在与试验数据对比的基础上,对影响该连接性能的主要参数如顶底角钢厚度、柱翼缘连接螺栓与梁翼缘间的距离等进行分析,得到了其弯矩-转角曲线。It is presented an approach of refined parametric three-dimensional （3D） non-linear analysis for semi-rigid steel beam-column connection of top-seat-angle with double angle（ i. e. four-angle）. Based on comparison of its results with test data, the effect of several geometrical parameters on the behavior of the connection is analysed , such as thickness of the angle and the bolt gage on the column leg of the connection angles. By which, the moment-rotation curve of the connection is obtained.
