In this paper, the relation among the non-structural wall of wooden-framed houses, their calculated natural period and the maximum displacement of their seismic response is discussed using the lumped mass system model. The analytical model has the restoring force characteristic composed of bracing bearing walls and non-structural plaster board walls. The results may be summarized as follows: The maximum story drift at the 1st story is estimated by the wall-length ratio of bearing walls and non-structural walls. The maximum story drift at the 1st story has a tendency to be in proportion to the calculated natural period. It is necessary to consider the stiffness of non-structural walls when the natural period is calculated.
