In this paper, the seismic performance of wood-framed residential structures is investigated based on full-scale loading test and the experiment of various walls. As a result of the full-scale test, It was found that the story shear at the deformation angle 1/120rad. was recorded by 199kN, that is 3.6 times seismic capacity of shear coefficient Co=0.31. And the maximum story shear force was 308kN at 1/27rad. It corresponds to 1.4 in the base shear coefficient, which proved high capacity of resisting force. The share of horizontal force of braces had shifted from 20% to 50% according to the deformation. The shear ratio of braces was 50% or below until the maximum loading force. The resisting force capacity of the actual house was estimated by adding the capacities of each wall together. Taking account of only the capacities of brace walls, the estimated strength was about a half of the actual value. Adding the effect of gypsum boards on non-structural walls, it was precise in 80% until about 1/100rad.
