钢骨-钢管混凝土受弯组合柱受力性能的试验研究

Experimental research on mechanical behavior of bending circular steel tube columns filled with steel-reinforced concrete

本文通过钢骨-钢管混凝土组合柱受弯试验,分析了这种组合柱受弯的破坏形态、荷载-位移滞回曲线、承载力和延性等受力性能,并讨论了组合柱的弯矩-曲率曲线特性。

Based on the test of bending circular steel tube columns filled with steelreinforced concrete, the mechanical behaviors of the bending columns, such as the failure form, loaddisplacement circulation curve,bearing capacity and ductility, are analyzed. The momentcurvature curve behaviors of composite columns are discussed.
