【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。更多还原

【Abstract】 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.更多还原
