【摘要】 节点的半刚性对钢框架的内力、位移和结构的极限承载力的影响相当大,在钢框架设计中不能忽视。针对实际工程中采用的一种半刚性连接节点—T型钢连接,进行了极限承载力计算,通过比较节点各组成部分所能承受的荷载极限值,选取其中最小值作为节点的极限承载力。用此方法计算了2个不同的节点模型,与试验结果进行对比,算式可反应T型钢连接的实际工作性能。更多还原

【Abstract】 The behaviors of semi-rigid connections would make great effects on the behaviors of steel frames such as the internal forces,the horizontal deflection and the ultimate load-carrying capacity,which could not be neglected to design the steel frames.The ultimate load-carrying capacities of the T-stub connections that are regarded as semi-rigid ones applied in factual projects are calculated.Compared with the ultimate load-carrying capacity of its components,the minimum is useful.Two different specimens’ models of the connection are calculated.The results are compared with the experimental data,and they approximately reflect actual rotational behavior of T-stub connection.更多还原
