摘　　要： 介绍了有限元计算和荷载试验中得到的钢管混凝土柱环梁节点的力学性能和破坏形态 ,归纳了其抗剪环的设计、对钢管混凝土柱承载力的影响、低周反复荷载作用下的性能、在框支梁中的应用和抗弯、抗剪承载力设计方法等研究成果 ,并探讨了节点计算刚度选择。 The following research results about the RRCB Joint are concluded and presented: its mechanical behavior and destroyed form which are gained from infinite-elemental calculation and experimental load tests, the design method of its shear-force-resisted ring bar, its impact on the load bearing capacity of column, its performance under low-cycle loading, its application in the shear-wall-supported beam, and its design method of flexure and shear strength. Furthermore, three key problems are discussed, those are the choose of its calculating rigidity, the force-transferred mechanism between the reinforced-concrete ring beam and the steel tube, and the twisting stress distribution in the ring beam.
