The evaluation of earthquake resistant capacity of traditional timber houses in consideration of the floor stiffness and grid lines of bearing walls is discussed. The result may be summarized as follows: The ultimate horizontal resistant force with hard stiffness floor is estimated from the one with soft stiffness floor. The minimum value of partial wall-length ratios of the resisting wall is independent of the wall-length ratio of the resisting wall. The resistant force calculated with the minimum value of partial wall-length ratios of the resisting wall has less error than the one calculated with the wall-length ratio of the resisting wall in comparison with the ultimate horizontal resistant force.
