摘　　要：某优秀历史建筑,因已使用80余年,存在明显结构老化、损伤,需要进行加固并重新装修。对原有建筑进行现场检测和抗震鉴定,基本符合我国现行各项规范要求。基于结构原有钢构件锈蚀、保护层剥落和抗侧力不足等实际情况,制定加固改造设计方案,提出增加剪力墙并对其下基础进行加固、外粘钢法和粘贴碳纤维布补强原有型钢梁、柱的加固措施,对加固改造后的结构进行了抗震验算分析,施工时采取沉降观测,改造效果良好。An excellent historic building has been used for 80 years, there are damages and obvious structural aging , which need to be reinforced and renovated .The field testing and seismic qualification were done for the original building, whose results could basically meet the requirements of the current norms in China .Based on the actual situation that the original structural steel members were corroded , protection layer falled off and resistance to lateral force was insufficient , it was developed a reinforcement design scheme , and proposed the measures of adding shear-wall and reinforcing its base , sticking steel plate outside and affixing carbon fabric to reinforce the original steel beams and columns .Then checking was carried out for seismic analysis of the reinforced structure the settlement observation was done during construction , the reform effect was excellent .
