摘　　要：通过3个带抗剪环的钢管混凝土柱环梁节点单调直剪试验,对设置抗剪环环梁的极限直剪承载能力、环梁的宏观受力表现、受力过程中环梁相对钢管的滑移以及环梁的最终破坏形态等进行了分析研究。试验结果表明,环梁节点的破坏模型及承载力计算还有待进行更深入的试验及分析研究。In this paper, through direct shear tests on 3 steel tube confined concrete column ring beam joints with shear ring, the ultimate capacity, the mechanical mechanism, the sliding of ring beam relative to steel tube and the ultimate failure mode of ring beam were analyzed. The results showed that the ultimate failure mode and the calculation of capacity of ring beam joint awaited further tests and analysis.
