具有抗裂柱墙体的抗温度应力分析

Analysis of resisting column improving ability of resisting temperature stress of mix structure wall

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 .

Resisting crack columns set in the walls can improve the resisting shear ability of walls. Resisting crack columns are most possibly set on the two ends of the building structure. Among the resisting crack columns, the resisting shear ability of walls can be considered to frame and wall cooperating together when the space among the resisting crack columns is small and there are at least two resisting crack columns in the walls. When the space is smaller, the proportion of bearing shearing of resisting crack columns is added. When the section area of resisting crack columns and ring girder is added, the proportion of bearing shearing of resisting crack columns is increased. Effect of intensity degree of brick and sand slurry is not obvious.
