摘要
采用有限元方法对7根T形截面的钢骨-方钢管混凝土组合异形短柱的轴压性能进行分析,通过全过程分析的荷载-位移曲线和相关应力云图,研究组合异形柱的破坏形态,分析混凝土等级强度、配骨率和套箍指标等参数对试件轴压性能的影响。结果表明:这种新型的组合异形短柱具有良好的轴压性能,可为工程实践提供参考。
The finite element method was used to analyze the axial compression performance of 7 T-shaped steel-reinforced concrete-filled steel tube concrete special-shaped short columns.Through the whole process analysis of the load-displacement curve and related stress cloud diagram,the failure form of the composite special-shaped columns was studied.Analyze the influence of concrete grade strength,bone distribution rate and hoop index on the axial compression performance of the test piece.The results show that this new type of combined special-shaped short column has good axial compression performance,and can provide a reference for engineering practice.
