[提要]  针对钢管混凝土柱-RC环梁节点型式，通过对边柱、中柱、角柱处采用三种不同型式钢管混凝土柱-环梁节点的受力性能进行了实体有限元分析，并参照有关试验结果，分别对三种不同型式节点在梁端弯矩剪力作用下，环梁截面内的扭矩、弯矩和剪力提供了实用的计算方法，为这类结构的设计提供了依据。

Abstract:  Steel tube confined concrete- RC ring beamjoint is a new type of joint in steel tube confined concrete structure. The analysis method of solid finite element is applied for study on bearing performance of several different steel tube confined concrete-RC ring beam joint including side column, inner column and corner column. On the base of the calculation and experimental results, the practical convenient method for designing such ring beams is put forward.
