摘要
针对实际在役建筑物中出现的剪力墙开洞问题,采用PKPM建立了剪力墙开洞前后的模型,通过开洞前后剪力墙配筋率的差值,运用等强代换的方法对开洞剪力墙进行粘钢加固,从加固前后结构的周期比、层间位移角、位移比、剪重比、刚重比、抗剪承载力等指标来验证加固效果.研究结果表明:该实际工程中剪力墙开洞后墙体的配筋率减低较多,需要补强;采用粘钢加固,加固前后结构的周期比、层间位移角、位移比、剪重比、刚重比变化较小,抗剪承载力满足要求;采用该加固方法弥补了06SG 311—1图集中关于剪力墙开洞加固区域的不足,可以运用到实际工程中.
With problems of shear wall with openings appearing in existing buildings,I analyze its impact on the overall structure by PKPM after the openings of shear wall,and foucs on bonding steel to reinforce shear wall with openings by the method of iso-strength exchangable.From the natural period,and displacement of the structure,and the ratio of rigidity-to-gravity,and the shear bearing capacity to verify the reinforcement effect.The results show that reinforcement ratio of the shear wall with openings reduced more,need reinforcement.The shear wall with openings bonded steel reinforcement has less effect on the overall structure in the actual engineering,which is even able to reach the level before its opening.Using this kind of bonding steel strengthening method makes up for short of atlas of 06SG311-1.Therefore,this method can be applied to the actual project.
