摘　　要：本文首先CFRP-钢管混凝土针对该种构件的轴压构件进行工作机理分析。然后在实验基础上着重分析了长细比、偏心率、约束系数等影响CFRP-钢管混凝土偏压构件的力学性能关键因素。分析了各个影响因素对构件极限承载力的影响;得出结论 CFRP在限定的长细比和偏心率等影响因素条件下提高钢管混凝土偏心受压构件的承载力。This article firstly analyzes the mechanism of this axial compressed construct. Then it presents the effect of the slenderness ratio and eccentricity, restraint coefficient on the capacity of structure. It is to draw a Conclusion that CFRP in a limited amount of slenderness ratio and eccentricity ratio influence factors can improve the bearing capacity of concrete-filled steel tube eccentric compression member.
