| 摘 要： | 介绍了CFRP-钢管混凝土组合短柱的制作流程,通过8根CFRP-钢管混凝土组合短柱和4根钢管混凝土组合短柱的轴向极限承载力的试验研究,来了解CFRP-钢管混凝土组合短柱的受力特性,并对这两种组合短柱在轴向荷载下的荷载-应变关系曲线进行比较,发现CFRP会使组合柱在屈服后的曲线有一个下降后又缓慢上升的过程,其程度会随着CFRP的层数改变.给出了外围钢筋混凝土套筒对CFRP-钢管混凝土组合短柱承载力的增强效果曲线以及钢管和CFRP的荷载-应变关系曲线,结果表明:钢管和CFRP可以保持协同工作.

| Abstract: | The process of making stub columns reinforced by concrete filled circular CFRP-steel tube was introduced.The characteristics of stub columns reinforced by concrete filled circular CFRP-steel tube was disdcussed based on the strength tests of 8 concentrically compressed stub columns reinforced by concrete filled circular CFRP-steel tube and 4 concentrically compressed stub columns reinforced by concrete filled circular steel tube.The load-strain curves of the two columns when compressed concentrically were compared.The enhancement curves of the outer concreter to ward the ultimate strength of concrete filled circular CFRP-steel tubular stub columns as well as the load-strain curves of CFRP and steel tube were demonstrated.It was found that steel tube and CFRP could work well together. |
