Abstract
In this paper, the distribution of maximum displacement responses of traditional timber houses is calculated in consideration of both floor stiffness and non-structural walls. The results may be summarized as follows: the floor stiffness is not a significant parameter of the maximum displacement response. The approximate excressions are presented in relation to the ultimate horizontal resistant force and the amount length of structural wall. The maximum displacement response in consideration of both floor stiffness and non-structural walls is approximately estimated as 1.15 times of the maximum displacement response calculated by the lumped mass system model.
