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.
