The vulnerability function of wooden-frame houses using the results of seismic diagnosis and a response spectrum was proposed. It employs a probability density function of seismic performance indices of wooden houses, which are separated into an index of horizontal resistance force and other indices. The input seismic motion is evaluated based on an acceleration response spectrum and natural periods determined by indices of horizontal resistance force. The application results to the 1995 Hyogo-ken Nanbu earthquake are compared with the damage statistics at the five sites, which have seismic records. Though the proposed vulnerability function is not based on the damage statistics, the estimated ratios for minor and more damages coincide fairly well with the actual damage surveyed by local governments.
