摘要
采用ANSYS对纤维布约束钢筋混凝土柱的轴心受压性能进行了非线性分析,并与试验结果进行了比较。分析结果表明,通过合理选择有限元分析数值模型,可较好地预测纤维布约束混凝土柱的轴心受压性能。根据数值分析结果,对其受力机理进行了探讨,揭示了纤维布与混凝土在轴压下的相互作用,为模拟钢筋混凝土结构的受压性能提供了新的方法和途径。
Nonlinear analysis for the behaviors of the fiber reinforced polymer--confined reinforced concrete columns under axial loads is studied by using the large general structural analysis software ANSYS in the paper. The computing results are compared with test ones. The former can simulate the behaviors of the columns with proper numerical model. The interaction between FRP material and con- crets is discussed based on the numerical results. The results indicates that the precision of model is high which provides a new method and approach to simulate the mechanic capability of reinforced concrete and has practical value.
