| 摘 要： | 通过截面经圆弧化处理、外包CFRP后的矩形截面的钢筋混凝土柱的轴心受压试验，研究了长细比对稳定承载力的影响。利用稳定理论中的切线模量和双模量理论，对CFRP强约束混凝土轴心受压柱的稳定性能进行了分析，并与试验结果进行了对比，提出了CFRP强约束混凝土轴心受压柱的长细比限值和相应的稳定承载力计算公式。

| Abstract: | By the axial compression tests of reinforced concrete slender columns wrapped withcarbon fiber reinforced plastics,while the column has elliptical section,study slenderness influence on the stable bearing capacity of the column.In terms of the tangent modulus theory and two modulus theory,the capacity-slenderness ratio curve in theory was calculated and compared with the experimental curve.At last,the simplified calculating formulas of axial-compression reinforced concrete column wrapped with CFRP and the slenderness Limit for reinforced concrete columns were proposed.It can provide a reference for engineering designers. |
