FRP管-钢管双壁约束混凝土组合柱轴压性能有限元分析

Finite Element Analysis of Axial Compression Performance of FRP Tube-Steel-wall Double-wall Confined Concrete Composite Columns

文章以已有文献中FRP管-钢管双壁约束混凝土组合柱的轴压试验为基础,利用有限元分析软件ANSYS建立了组合柱的轴心受压数值模型,对比分析显示,有限元计算结果与试验结果吻合得较好,为今后该组合柱的研究提供了参考。

Based on the axial compression test of FRP pipe-steel double-walled confined concrete composite columns in the existing literature, a numerical model of the axial compression of the combined columns is established using the finite element analysis software ANSYS. The comparison analysis shows that the finite element calculation results are in good agreement with the experimental results, which provides a reference for the future study of the composite column.
