摘　　要：以某县税局办公楼加固项目为例,对框架式结构加固方法进行设计。首先介绍了加固对象的基本情况,并针对该框架结构不满足抗震需求这一不足,进行加固设计,然后通过对结构柱、梁和基础的具体加固措施与工艺进行介绍及分析,指出了加固过程中需注意的细节,最后通过有限元软件计算结构加固后的各项抗震指标,结果表明,加固措施能够有效提高原有结构的抗震性能,满足抗震需求。Taking the reinforcement project of an office building of a county tax bureau as an example,this paper designs the reinforcement method of frame structure.Firstly,the basic situation of the reinforcement object is introduced,and the reinforcement design is carried out in view of the insufficiency that the frame structure does not meet the seismic requirements.Then,through the introduction and analysis of the concrete reinforcement measures and processes of columns,beams and foundations,the details that should be paid attention to in the reinforcement process are pointed out.Finally,the seismic indicators of the strengthened structure are calculated by the finite element software.The results show that:this reinforcement can effectively improve the seismic performance of the original structure and meet the seismic requirements.
