[摘要] 某五层居民楼建于上世纪60年代，上部结构形式为底框架砖砌体结构。该建筑已接近设计使用年限，为确保其抗震性能和安全使用要求，有必要对其进行抗震鉴定。首先对该建筑从宏观控制和构造鉴定方面进行第一级鉴定，然后运用楼层综合抗震能力指数法进行第二级鉴定，最后给出鉴定结论，并提出加固建议。

Abstract: A bottom frame with five stores was constructed in 1960s.  The building has been close to design service life. In order to ensure the seismic bearing capacity and safety requirements for using, it is necessary to carry on the seismic appraisal. The first level appraisal was carried from the macroscopic control and conformation identification, and then the second level appraisal by the floor comprehensive seismic capability index method, finally the seismic appraisal results and strengthening proposal were presented.
