Abstract:A three-level seismic performance investigation method for rural residences was put forward to apply in the rural residences in three districts and counties in Tianjin area, and the basic principle of applying the three-level investigation method was expounded. According to the requirements of seismic fortification in rural areas of Tianjin, the seismic fortification parameters of three districts and counties were given. According to the survey of more than 20 000 rural residences, the seismic status of rural residences was analyzed. According to the strength of mortar and seismic structural measures of load-bearing walls of rural residences, the spatial and temporal distribution of structural characteristics of rural residences was analyzed. The seismic statuses of adobe, stone, brick-wood and brick-concrete structures were analyzed to provide technical support and scientific basis for seismic safety of existing rural residential structures.

Keywords:rural residential structure; seismic investigation; seismic performance; seismic status
