中文摘要：
本文对采用顶底角钢连接的半刚性钢梁柱连接节点进行了精细的三维非线性有限元分析，在与实验数据对比的基础上，对影响该连接性能的主要参数如角钢厚度、柱翼缘连接螺栓与梁翼缘间的距离等进行了分析，得到了其弯矩-转角曲线。
英文摘要：
This paper presents an approach to the refined parametric three-dimensional non-linear analysis of the semi-rigid steel beam-column connections of top-seat-angle. Models drawn from the previous experimental study of top and bottom seat angle connections are generated to compare the analysis results with the test ones, and an accurate prediction is made by 3D refined models. The effect of several geometrical parameters on the overall moment rotation response, such as the thickness of the angle and the bolt gage on the column leg of the connection angles is analysed.
