摘要
钢管混凝土框架结构中梁柱的连接往往是半刚性的,设计中把梁柱连接假定为完全刚接或完全铰接都是不合理的。探讨了半刚性连接对钢管混凝土框架结构内力、位移等的影响,导出了半刚性连接钢管混凝土框架结构在竖向荷载下梁端弯矩的求解公式,对水平荷载作用下标准反弯点高比计算公式进行修正,并提出了考虑半刚性连接的设计建议,可供工程设计人员参考。
Generally the beam-column connections of concrete filled steel tube frame are semi-rigid. It was unreasonably to assume that the connections were rigid or normally pinned in design. Such effects as internal force and displacement that the semi-rigid connections had on the concrete filled steel tube frame were discussed. The formulas used to solve the beam moment under vertical load were deduced; furthermore, the formulas to determine the height ratio of standard inflection point were modified. Design suggestions on considering the semi-rigid connections have been made. The proposed methods may supply references for the engineers of semi-rigid concrete filled steel tube frame structure design.
