【摘要】 以"T型件"作为基本分析单元,利用组件法,分别给出了各组件的刚度计算方法,如柱壁抗压刚度、柱壁抗剪刚度、端板抗弯刚度、柱壁抗弯刚度、混凝土楼板抗压刚度、螺栓抗拉刚度,提出了正弯矩作用下端板连接半刚性钢管混凝土组合节点初始刚度计算公式。通过试验验证了所提组合节点初始刚度简化计算方法的正确性和准确性。更多还原

【Abstract】 Selecting T shaped component as basic element and using the component method,the calculated method of initial stiffness of semi-rigid CFST composite joints under positive moment is obtained. Some components were given,including column wall compressive stiffness,column wall anti shear stiffness,end plate bending stiffness,column wall bending stiffness,concrete slab in compression stiffness and bolt tensile stiffness. The correctness and accuracy of the simplified calculated method of initial stiffness of semi-rigid CFST composite joints are verified by experiments.更多还原
