CFRP-圆钢管混凝土偏压柱承载力回归分析

摘要

根据16根CFRP-圆钢管混凝土偏压柱承载力的试验研究,对CFRP-圆钢管混凝土偏压柱的受力性能及工作机理进行简要分析;并且以钢管混凝土理论计算及CFRP-圆钢管混凝土轴压短柱理论计算为基础,回归出CFRP-圆钢管混凝土偏心受压构件的简化计算式;应用简化计算式的计算结果与实验结果吻合良好且偏于安全,满足工程需要。%Based on the experimental study about 16 circular concrete filled CFRP-steel tubular columns,the properties and working mechanism under load of concrete filled CFRP-steel tubular columns was analyzed.And based on the theoretical analysis of the circular concrete filled CFRP-steel tubular columns,the simplified calculation equation was returned.Through the compare of the calculation results and experimental results,an approving conclusion is obtained.These results testified the validity and the feasibility of the modeling method.
