对建筑物女儿墙开裂原因的分析

Analysis of the cause of the split of parapet wall

通过对一个工程实例的定量计算,从理论上对女儿墙开裂这一较普遍的现象进行了分析,得出了屋面板因热胀冷缩而使女儿墙受到剪拉应力大于女儿墙抗剪强度时,是其开裂原因的结论,并提出了解决的方法。

This paper is to make analysis of a common phenomenon, the split of parapet wall. On the basis of calculation of a practical project, a conclusion is that shear strength on parapet wall is stronger than the shear resistance of parapet wall because of the roof panel＇ s expanding with heat and contracting with cold. And in the end a solution is put forward.
