摘　　要：结合实际工程,对钢结构规范中没有规定的圆主管和方支管的相贯节点算法,提出了一些思路及处理方法,指出可采用规范的等效算法,对设计承载力乘以折减系数,并通过在节点处增设加劲肋来解决应力集中现象。Combined with practice, it puts forward some thinking and procexsing methods to the relevant tubular joints calculation method of the round main pile and square brunch pipe which are not included in steel-strueture norm, points out that standard equivalent-effect calculation method can be taken to multiply designed loading capacity by reduction factor and ribs can be added at joints to solve stress concentration.

关 键 词：圆主管与方支管的相贯 K型节点 KK型节点
