【摘要】 通过9根FRP管混凝土组合柱试验结果的验证,确立了ABAQUS有限元分析模型和相关参量的取值。在此基础上,进一步分析了纤维铺设角度、长细比等参数对组合柱轴压性能的影响。分析表明:组合短柱的承载力与纤维铺设角度呈非线性关系,变化情况为先增大后变小,且最佳纤维铺设角度在14°左右;长细比对组合长柱轴压性能影响很大,组合长柱极限承载力随长细比的增大有较明显地线性减小趋势,对深入研究FRP管混凝土组合柱的轴压受力性能提供一定的参考。更多还原

【Abstract】 By verifying the experimental results of 9 FRP tube concrete composite columns,finite element analytical model and the values of relevant parameters were established.Based on analytical method,finite element software ABAQUS further analyzed the effect of fiber orientation and slenderness ratio on axial compression property of composite column.The results show that bearing capacity of composite short columns and fiber orientation indicate nonlinear relationship,the curve increases at first and then decreases,what’s more,the best fiber orientation is about 14°;slenderness ratio influences axial compression properties of long composite columns a lot,the data from finite element also shows that bearing capacity of long composite columns decreases obviously with the increase of fiber orientation,in addition,all results can give some reference for further research of axial compression property of FRP tube concrete composite column.更多还原
