摘要:
以钢管混凝土柱-钢梁单边螺栓连接节点往复加载试验研究为基础,采用ABAQUS软件建立非线性有限元模型,探讨节点核心区构造措施对节点弯矩-转角曲线的影响规律.研究结果表明:节点核心区外焊槽钢或内置短H钢能显著提高节点抗弯承载力;加强型单边螺栓连接节点为半刚性连接、部分强度节点;增大外槽钢厚度、外槽钢强度、内H钢厚度、内H钢强度均能有效提高节点抗弯承载力.
Abstract:
Based on the cyclic loading experiment of concrete filled steel tubular column(CFST)-steel beam blind bolted joints, nonlinear finite element models were built by ABAQUS software, the influence of reinforcing components on bending moment-rotation curves were discussed. The research results show that, the flexural bearing capacity of the joints can significantly enhanced with welding channel or installing inner H steel. The reinforced joints can be classified as semi-rigid and partial strength connection. The flexural bearing capacity of the joints can be improved with the increase of the thickness or the strength of channel steel, the similar effect can be achieved by increasing the thickness of inner H steel or increasing the strength of inner H steel.
