摘　　要：利用ANSYS模拟四根不同配箍率的高强混凝土轴压柱,分析了各柱的裂缝图和应力应变曲线。结果表明,随着配箍率的增加,柱的延性和承载力可以得到提高;较好的验证了文献中的箍筋作用机理。Four confined concrete columns were simulated under uniaxial compression by ANSYS. The complete stress - strain curves and Cracks in Figure of every column were analyzed. The results show that ducility and Carrying Capacity were improved with the increase in hoops and the Stirrup mechanism were tested and verified in certain literature.

关 键 词：轴压柱 应力-应变全曲线 配箍率 延性
