【摘要】 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,在与试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。更多还原

【Abstract】 It is presented an approach to refined parametric three-dimensional(3D) non-linear analysis of semi-rigid steel beam-column connections of top-seat-angle.Models drawn from a previous experimental study of top and bottom seat angle connections are generated in order to compare the analyses with test results,with good prediction shown by the 3D refined models.The effects of several geometrical parameters on the overall moment-rotation response are analysed,such as thickness of the angle and the bolt gage on the column leg of the connection angles.更多还原
