| 摘 要： | 目的 研究碳纤维布加固砖砌体墙的抗震受力性能及不同的碳纤维布粘贴方式对砖砌体墙抗剪承载能力的影响,提出纵横粘贴碳纤维布和四面围束粘贴碳纤维布的方法.方法 对比交叉粘贴碳纤维布和横向粘贴碳纤维布,采用有限元分析软件ANSYS,模拟各种不同的碳纤维布粘贴方式,并对墙体和碳纤维布分别进行应力分析,对各种碳纤维布粘贴方式的抗剪承载力进行计算和比较.结果 交叉粘贴碳纤维布的墙体抗剪承载力较未加固墙体提高了5.6%,横向及纵横向粘贴碳纤维布加固墙体的抗剪承载力分别提高了11.4%～20.4%.四面围束粘贴碳纤维布加固墙体的抗剪承载力提高了20.3%.结论 在砖砌体墙表面粘贴的碳纤维布能够提高墙体的抗剪承载力,增加墙体的整体性,改善墙体抗震受力性能;纵向粘贴碳纤维布能够有效控制横向碳纤维布的剥离.
