The seismic reinforcement design of existing buildings has a wide range of application prospects, and the selection of reasonable structural system reinforcement scheme is the focus of seismic reinforcement design.The research direction of this paper is to obtain a better seismic strengthening method of single span frame structure with overhanging veranda in primary and secondary schools, and to provide a better seismic reinforcement design scheme for this kind of existing buildings.The main conclusions of this paper are as follows: the three strengthening schemes can reduce the seismic response of the structure, reduce the deformation of the structure under the earthquake action, and improve the seismic performance of the structure.Among them, the shear wall (SW) scheme can significantly reduce the deformation of the ground floor structure, and the isolation bearing (ISO) scheme has the best effect on reducing the overall deformation.But in the specific project operation, we should consider the project budget and time cost and other factors, and use the reinforcement scheme reasonably.
