摘　　要：为了解建于1988年的某9层板柱-抗震墙结构书库楼板裂缝成因,开展现场检测与抗震鉴定,并评估楼板裂缝对结构安全性能的影响。根据鉴定结果提出相应加固措施,以保证结构安全。研究结果表明,楼板裂缝是由构造缺陷、荷载作用、施工缺陷等综合因素引起的受力裂缝,同时房屋抗震性能存在一定缺陷。In order to research the causes of floor cracks of a 9-story slab-column-shear wall structure bookstore built in 1988,on-site inspection and seismic identification were carried out,and the impact of floor slab cracks on structural safety performance were assessed,and corresponding reinforcement measures were proposed according to the identification results to ensure structural safety.The research results show that the floor slab cracks are force cracks caused by a combination of structural defects,load effects,construction defects,etc.,while there are certain defects in the seismic performance of the house.
