摘　　要：研究采用环梁和环形钢筋加强节点区的新型节点形式 ,通过试验验证这种新型节点的可行性 ,并对节点区的加强环形钢筋的受力特点进行讨论 .In this article, the research on the new joint which is strengthened by the ring beam and reinforcing ring bars is carried out. The experiment results are used to verify the feasibility of the joint structure, and the mechanics feature of the ring bars in joint zone is discussed.

关 键 词：钢管混凝土桩 梁节点 节点性能 环形钢筋 轴向承载力 钢筋应变特点 破坏过程
