Abstract: By the FEM analysis on the elastoplastic dynamic about a rural housing with hybrid structure, we observedstress variation of the rural housing under the earthquake excitation, and found that the comers of the doors and windows, walls between windows, the window belly wall and columns of bottom frame are the weak parts, and analyzed the ring beams and constructional columns' enhancement of the house'  aseismic capacity. The results have certain value for fruther study and seismic reinforcement.
Keywords: aseismic performance; rural housing; finite element method; non-linear
