摘　　要：以主拉应力破坏理论为基础,分析了在水平地震作用下,墙体内一点的主拉应力方向与该点水平剪应力和垂直压应力比值之间的关系,试验研究表明碳纤维布能够有效分担部分墙体拉应力.针对不同类别的建筑物墙体,建议按其主拉应力方向粘贴碳纤维布.Based on the failure theory of principal tensile stress, the relationship between the point＇s principal tensile stress orientation and the ratio of horizontal shearing stress to vertical compressive stress is analyzed in the horizontal earthquake. The experimental research shows that carbon fiber sheet can take partial tensile stress of the wall. This paper puts forward the reinforcement suggestion of bonding carbon fiber sheet along the principal tensile stress orientation according to different building walls.
