This paper adopts carbon fiber cloth outsourcing and steel plate reinforcement technology to strengthen the structure of a brick and concrete structure office in the 1950s.Through finite element analysis and field detection,the structural performance changes before and after reinforcement.The results show that the carbon fiber cloth outsourcing can improve the bearing capacity of components,and the steel plate reinforce-ment can increase the stiffness of beam and column joints.After the renovation,the seismic performance of the building is improved and the service life is extended,which provides a reference for the renovation project of similar old buildings.
