钢管混凝土柱-钢梁节点抗震性能研究
The Experimental Research on Cyclic Behavior of Beam-CFST Column Connections
摘要:
随着住宅钢结构的推广发展，钢管混凝土柱与梁、板等水平构件的连接形成重要的结构体系，特别是形成抵御地震作用的抗侧力体系。因而钢管混凝土节点的计算方法和构造措施是设计中非常关键的环节。本文研究了节点的应力分布规律，得到了荷载位移曲线、节点的屈服强度。分析表明，填充混凝土的扁钢柱节点具有较好的刚度和延性。
Abstract:
In recent years, with the promotion and development of steel structure in residential market, concrete filled steel tubular column is formed by the reliable connection of the horizontal compo-nent such as beam and plate. The calculation method and construction measures of concrete filled steel tubular joints are the key problems in design. In this paper, the stress distribution of the joint is studied. The load-displacement cures of the joints are obtained, as well as the yield strength and the ultimate strength. It indicates that joints filled with concrete have preferable stiffness and ductility.
