在墙体中增设抗裂柱可以提高墙体的抗剪能力 ,并且抗裂柱应尽可能布置在房屋结构的两端部分的墙体内 .当墙段中有 2根以上抗裂柱 ,且抗裂柱间距较小时 ,在抗裂柱间距范围内 ,按照框架—砖墙协同工作考虑墙体的抗剪能力 .对典型墙体抗剪能力分析表明 ,抗裂柱间距减小 ,在抗裂柱范围内由抗裂柱承担的剪力比例增加 ;抗裂柱及圈梁截面面积增大 ,在抗裂柱范围内由抗裂柱承担的剪力比例增加 ;砖及砂浆的强度等级对抗裂柱范围内抗裂柱及墙体承担的剪力分配影响不大 .
The addition of anti-cracking columns in the wall can improve the shear resistance of the wall, and the anti-cracking columns should be arranged in the walls of both ends of the house structure as much as possible. When the wall segment has more than two anti-cracking columns, and When the distance between anti-splitting columns is small, the shear resistance of the wall is taken into account in the framework of the anti-splitting column spacing, and the shearing capacity of the wall is taken into account in the cooperation of the frame and the brick wall. The analysis of the shear resistance of the typical wall shows that the spacing between anti-cracking columns is reduced and the crack resistance is reduced. The proportion of the shear force assumed by the anti-crack in the column increases; the cross-sectional area of the anti-crack column and the ring beam increases, and the shear ratio assumed by the anti-crack column increases within the anti-crack range; the strength grades of the brick and mortar resist cracking. The influence of shear distribution on the columns and walls of columns is not significant.
