摘　　要：通过大量的有限元计算,对T形,Y形节点的几何参数进行了分析,引入修正函数对T形节点计算公式进行修正,经回归分析确定Y形节点有限元计算结果与相应T形节点公式计算结果的比例关系,并得到Y形等宽矩形钢管相贯节点受弯承载力计算公式。Based on the study of the load-carrying capacity offight angle T-joints under in-plane bending,with a host of the finite element analysis results,the geometric parameter of T and Y joints are analysed,according to the results of analysis,amendment functions for amend the T-joints calculation formula of carrying capacity are indrafted.Based on the formula,ascertain the proportional relation between T and Y joints,and then got the calculation formula of carrying capacity of full-wide Y-type RHS joints under in-plane bending.
