摘　　要：结合工程实例,介绍了某底层内框架结构抗震鉴定的内容与方法,包括结构完损检测、材料强度、建筑倾斜情况等。分析计算了结构现有的抗震承载力,并在此基础上提出了具体的加固措施,包括改变结构形式法、加大截面法、碳纤维加固法及增设构造柱等,以期为类似工程的抗震加固提供参考。Based on an engineering project,the methods and contents of seismic identification for the bottom frame structure were introduced,including the structure damage detection,strength of materials,and construction condition of inclination.The existing seismic capacity of the structure were calculated,and by analyzing the testing results,several strengthening methods were taken,such as changing structure shape,enlarging section,reinforcing with carbon fiber and adding constructional columns,and it can provide references for similar project.

关 键 词：底层内框架结构 抗震鉴定 加固措施
