摘   要：采用ANSYS软件对玄武岩纤维布（BFRP）约束钢筋混凝土方柱的轴心受压过程进行了数值模拟, 得到了BFRP约束混凝土柱的应力分布和裂纹发展情况，并与试验数据进行了对比分析。结果表明, 选择分离式有限元数值分析模型, 可较好地模拟BFRP 布约束混凝土柱的轴心受压性能。基于模拟结果，本文对BFRP 加固钢筋混凝土方柱轴压破坏过程进行了受力分析,探讨了BFRP 布与混凝土在轴压下相互作用的机理。

Abstract：he process of axial compression of the basalt fiber (BFRP) confined reinforced concrete columns is simulated by using ANSYS software, and the stress distribution and crack development of basalt fiber (BFRP) confined concrete columns are obtained, which are compared and analyzed with the test results. The results show that the discrete model for finite element numerical analysis can simulate the axial loaded behavior of BFRP confined concrete columns. Based on simulation results, the force analysis of the failure process of BFRP confined reinforced concrete square columns is taken and the interaction mechanism between BFRP cloth and concrete under axial compression is discussed.
