| 摘 要： | 将CFRP(碳纤维复合增强塑料)应用于钢管混凝土结构,对CFRP-钢管混凝土轴压短柱的受力性能进行了简要的理论分析;应用塑性全量理论的Hencky应力应变关系来确定钢管进入塑性后CFRP-钢管混凝土构件的极限承载力,推导出碳纤维拉断时构件极限承载力的解析计算式;并将解析分析结果与试验数据比较。

| Abstract: | CFRP(carbon fiber reinforced polymer) is integrated with concrete filled steel tubes structure and a theoretical analysis is carried out for the load carrying capacities of the axially compressed concrete filld CFRP-steel tube;the ultimate bearing capacity of concrete filled CFRP-steel tube is gotten after the steel tube is plastic with the theory of Hencky's plasticity.The equation is derived for estimating the bearing capacities of the system in the case of CFRP-sheet breaks;the experimental data are compared with the analytic results. |
