摘要
通过对某单层厂房大跨SP预应力空心板对承重墙体的裂缝损伤分析 ,讨论了此种墙体裂缝的特点及产生原因 ,并提出了可行的加固方案。最后提出了避免墙体出现这种裂缝的措施 ,可供设计和制定SP预应力空心板标准图集参考。
On the basis of the analysis of crack damages of the main walls due to large-span SP prestressed hollow slab for a single-story workshop, the characteristics and the causes of the cracks in the walls were discussed in this paper, and a feasible reinforcing scheme was presented. A precaution was put forward which can be regarded as a reference for designing and establishing of standard collective drawing of SP prestressed hollow slab.
