This study aims at showing the availability of linear and nonlinear viscous dampers in reducing seismic response of wooden houses. In this paper, proposed is a simple and practical method to determine amount of the damper needed to achieve the target distribution of story deflection. The method makes use of the limit strength calculation specified in the Japanese seismic design code. The method consists of two steps: First, described is a procedure for estimating damping coefficients of linear viscous dampers required in each story to satisfy target maximum deflection. Then, damping coefficient of linear and nonlinear viscous dampers are determined. Maximum deflections of a two-story wooden house obtained by the proposed method are confirmed to be in good agreement with those by time history seismic response analyses. It is also confirmed that strengthening of houses with proper amount of viscous dampers will not result in excessive acceleration response.
