| 摘 要： | 采用多轴应力下Ottosen混凝土应力-应变关系及Ottosen破坏准则,以核心混凝土与FRP约束层变形协调为边界条件,通过编制程序对FRP约束混凝土轴压短柱应力-应变关系曲线进行了计算,并与试验结果进行了对比,结果表明理论计算方法与实验结果吻合良好.

| Abstract: | The stress-strain curves of FRP-confined concrete columns were plotted by calculation using a computer program under the boundary condition of corresponding distortion between core concrete and FRP confining layer analyzed by the Ottosen's failure criterion and stress-strain relationship of concrete in triaxial states. Compared with experiment results, the theoretical results agree well with the experimental curves. |
