Seismic performance of 72 two-story wooden houses build in Sapporo was grasped from seismic diagnosis that considered snow depth on roof. Photos and drawings of the wooden houses for seismic diagnosis were obtained from an outside walls renovation company. Seismic reinforcement for the wooden houses was estimated from evaluation of the seismic diagnosis. The results indicate as follows: for the seismic diagnosis as the snow depth 0m, the evaluations in lots of the wooden houses were more than 1.0. As the snow depth more than 1.0m, the evaluations were small so that the seismic reinforcement is needed. Reinforcement for capital and column base by steel plates was assumed as the seismic reinforcement. To have improvement effect for the wooden houses having poor seismic resistant in the seismic reinforcement was clarified.
