摘要
为研究在钢筋混凝土剪力墙中配置碳纤维复材筋对剪力墙变形能力的影响,制作了1个普通钢筋混凝土剪力墙和1个碳纤维复材筋-钢筋混凝土剪力墙足尺试件,进行水平荷载作用下的拟静力试验,研究剪力墙的延性性能、耗能能力和侧向变形等。试验结果表明:与钢筋混凝土剪力墙相比,碳纤维复材筋-钢筋混凝土剪力墙的延性和耗能能力较低,但其极限变形能力较大,残余变形很小,具有优异的变形恢复能力。
In order to evaluate the effect of CFRP bar on deformation ability of the reinforced concrete shear wall, two full- scale test shear wails, one of them reinforced with steel bars and the other reinforced with steel and CFRP bars in the horizontal direction were fabricated and tested under reversed cyclic lateral loading. The ductility, energy dissipation and lateral residual deformations were researched. The test results indicated that the shear wall reinforced with CFRP bars and steel bars had lower ductility and energy dissipation as compared to shear wall reinforced with steel bars totally, however it had higher ultimate deformation capacity and small residual deformations, which demonstrated its excellent deformation recovery ability.
