摘　　要：以西藏某医院建筑改造为例,对既有多层框架结构加固改造进行探讨。通过对原结构进行分析和鉴定发现,原框架结构存在刚度偏小、承载力不足和构造不满足现行规范要求等问题;经对不满足要求的部分进行抗震加固设计,再次验算加固后建筑模型的各项性能指标。结果表明:建筑模型各项指标均满足现行规范要求。Taking a hospital building in Tibet as an example,the paper discusses the existing multilayer frame structure reinforcement and reconstruction.Through the analysis and identification of the original structure,the problems of original structure were found that smaller stiffness,bearing capacity of deficiencies and its structure did not meet the requirements of the current specification.After the seismic reinforcement design of the parts that do not meet the requirements,the performance indexes of the reinforced building model are checked again.The results showed that the building model the indicators meet the requirement of the current specification.
