【 摘 要 】

In order to study the deformation and stress distribution of confined concrete, the axial compression behavior of high-strength concrete column confined with high-strength stirrups is simulated through through nonlinear finite element program. The finite element model reflect the confining effect of high-strength stirrups in specimen. The calculated results shown that the deformation of stirrups is not equivalent in the cross section and the longitudinal section and the confined stress and axial stress of concrete is not uniform in the cross section.
