【摘要】 采用ANSYS有限元软件对方钢管混凝土框架梁柱常用的两种节点形式即栓焊混合连接和全焊接连接进行了三维实体建模 ,在此基础上利用非线性有限元方法研究了两种节点在低周往复荷载作用下的滞回性能 ,并对两种节点形式的抗震性能进行了比较 ,结果表明 ,全焊接连接节点的抗震性能优于栓焊混合连接节点。更多还原

【Abstract】 A three-dimensional real modelling of bolting-welding connection and full-welding connection of beam-column in concrete-filled rectangular and square steel tube (CFRST) frames is conducted using the finite element software ANSYS,based on which the hysteretic behavior of the two connections under low-cycle repeated load is studied using the nonlinear finite element method,whose aseismic performance is also compared. The results show that the aseismic performance of the full-welding connection is superior to that of the bolting-welding connection.更多还原
