The purpose of this study is to improve the prediction accuracy of the maximum deformation of the wood structure in time-history response analysis. We propose a method to examine a damping mechanism on the basis of energy response. First, in order to approximate damping energy of wood structure, we derive formulas for VD/VE =f(h)W or f(h,μ)W through the damping factor of wood structure. Equivalent velocity VE is converted from total input energy and equivalent velocity VD, from energy attributable to damage. Next, based on the assumption that the damping force is proportional to the relative velocity, we estimate the viscous damping coefficient by the relation between the relative velocity and damping energy calculated by the approximation formulas. Finally, we estimate the damping coefficient of full-scale wood structure frame by proposed method, confirming the validity of proposed method.
