摘要
高强螺栓端板连接节点,以其施工方便、抗震性能好,而在多高层钢框架结构中得到推广使用.因该类节点为半刚性,受力性能复杂,而目前国内规范对此类节点的设计方法缺乏具体的规定,从而限制了其广泛应用.本文通过数值模拟和试验方法,研究了两类螺栓端板连接节点的承载性能和刚度特征,得到了节点的弯矩-转角曲线,数值模拟与试验结果吻合较好,从而为这种节点的设计与应用提供参考.
The high strength bolt endplate joints have been used in popularity in multi-storey frames because they have the advantages of requiring shorter assembly times and better seismic performance than welded joints. However, the structural behavior and design of such connections, as semi-rigid, are relatively complex especially when detailed guides are not provided in current codes. The structural properties, both strength and stiffness, of two types bolt endplate joints were investigated by numerical simulation and experimental research in this paper. The moment-rotation curves were also described and agree well with the test results. Some conclusions drawn may be significantly useful for the design and application of such connections.
