摘　　要：利用外包碳纤维约束混凝土柱加卸载曲线的特点 ,得到了刚度与极限压应变均较大的刚性元件 ,并用该刚性元件测得了完整的混凝土应力 -应变全过程曲线 ,证实了此种刚元件是一种新型的较好的刚性元件。Aimming at the features of loading and unloading curve of restrained concrete columns wrapped with FRP,we fond a kind of rigid component with higher rigidity and ultimate compressive strain,and the total stress-strain curve were gotten by the help of it.It has proved that it is a kind of new-style rigid component.

关 键 词：纤维包裹 约束混凝土 刚性元件 全过程曲线
