| 摘 要： | 利用数值分析方法对钢管高强混凝土在轴心受压时的荷载－变形关系曲线进行了全过程分析。为了验证理论分析结果，进行了不同套箍系数的轴压标准试件的试验研究，计算曲线和试验曲线吻合。最后，提供了钢管高强混凝土轴压强度承载力的简化计算公式。

THEORETICAL ANALYSES AND EXPERIMENTAL RESEARCHES FOR THE BEHAVIORS OF HIGH STRENGTH CONCRETE FILLED STEEL TUBES SUBJECTED TO AXIAL COMPRESSION |
| |
| Abstract: | Integral method is applied for the analyses of complete curves of load-deformation and behaviors of high strength concrete filled steel tubes (HSCFST) subjected to axial compression Some HSCFST with different confining ratios ξ are tested in order toprove the corrections of the theoretical analysis results, and the theoretical results fit with those of tests satisfactorily Finally, simplified calculating formula of the strength of HSCFST is put forward |
