【摘要】 通过5片带壁柱的墙体试件(其中包括1个对比墙),主要研究了玻璃纤维复合材料(G lass F iber Re inforced Polym er,GFRP)加固后的墙体抗剪性能。结果显示,通过GFRP的加固,带壁柱砖墙的极限荷载、极限位移和抗剪刚度都有提高,但提高幅度随加固形式的不同而异。同时,如果对墙体进行不对称加固时,会有明显的墙体扭转及GFRP剥离现象,此时加固效果差。更多还原

【Abstract】 Through the experiment research on 5 walls(included 1 unreinforced wall),we mainly studied on the form and quantity of the reinforcement for the shear performance of the brick walls.The result showed: After reinforced with GFRP, the brick wall utmost load、utmost displacement and shear stiffness had been all increased,but the increase would be different for different form and quantity of the reinforcement.In the experiment: When the walls reinforced by unsymmetrical GFRP,the twist phenomena will occur,the effect of reinforce becomes bad and GFRP will peel.更多还原
