| 摘 要： | 钢管约束钢筋混凝土柱就是在普通钢筋混凝土柱外设置薄壁钢管,钢管在梁柱节点区断开,不直接承担纵向荷载,只对核心混凝土起约束作用。由于钢管不通过梁柱节点区,因此钢管约束钢筋混凝土柱与钢筋混凝土梁连接方便;且钢管约束钢筋混凝土柱承载力高,抗震性能优越,是一种具有广泛应用前途的新型组合结构形式。钢管约束钢筋混凝土柱在大连市体育馆工程中的应用,解决了钢筋混凝土超短柱抗震性能差的问题;且钢管约束钢筋混凝土柱的用钢量低,施工方便,经济效益和综合效益显著。

| Abstract: | A tubed RC column is a common RC column with an outer thin-walled steel tube shorter than the concrete part,so no axial load is transferred through the steel tube and the steel tube only confines the core concrete.Tubed RC columns connected conveniently with RC beams in respect that the outer steel tube does not pass through the beam to column connection.Tubed RC columns also exhibits excellent strength and seismic behavior,therefore it is a new kind of composite structure that can be widely used in civil e... |
