Abstract: The steps, contents and precautions of seismic appraisal and reinforcement of the common one and two storiesmasonry structures and wooden structures in the self?built houses by rural residents were mainly introduced. The appraisalcontent involves the determination of the follow?up service life, the collection of technical data, the investigation of buildingstatus, the investigation of the construction site, structural measures, appearance and internal quality inspection of masonrystructure houses, structural appraisal and appearance quality inspection of wood structure houses. The reinforcement ofthree situations of foundation cracking, insufficient bearing capacity and insufficient foundation bottom area wereexpounded. For the reinforcement of masonry structures, four methods were introduced, including reinforced mesh mortarsurface layer reinforcement, additional anti?seismic wall reinforcement, additional external ring beam reinforced concretecolumn reinforcement, and reinforced concrete slab wall reinforcement. For the reinforcement of wood structures, thereinforcement principle, reinforcement sequence, wood frame reinforcement, wood component reinforcement, andmaintenance brick walls reinforcement were introduced.

Keywords:self?built house by rural resident; seismic appraisal; reinforcement; masonry structure; wood structure
