摘　　要：运用弯剪共同作用理论分析了削弱半径对腹板开洞型节点的影响;利用非线性有限元方法分析了理论得出的结果,认为这一理论方法用于估计截面的抗弯能力以及确定腹板开洞型节点的临界削弱半径是有效的;并分析了削弱截面离柱距离与削弱半径的相互关系。对该类节点的设计具有一定的指导意义。The effect of cutting radius on steel reduced web connection is analyzed considering both the moment and shearing force. The result got from theory analysis is confirmed fight through non-linear finite element analysis and the theory is believed effective to estimate the moment resisting ability of steel beam section. Then the influence between the distance from column and cutting radius are analyzed. It is instructive for designing such reduced web connection.
