Most of the schools in Korea were designated as refuge facilities. It is, however, the fact that almost all of the reinforced concrete school structures have been old and were not built based on the seismic design codes. So far, a series of research dealing with development of seismic vulnerability assessment techniques have been carried out and some methods were recommended to evaluate the seismic performance which is one of the highly complicated multi-criteria evaluation problems. This study present a evaluation procedure of seismic performance modifying the previous method for the purpose of accuracy improvement, in addition, apply the modified procedure to grasp the seismic performance and predict the damage extent with or
without safety rate of the selected 22 school structures. And then, identify the applicability of this simple and rapid procedure by a comparative study of seismic and non-seismic designed school structures. The conclusions of this study are as follows : 1) the equation is proposed through relationship between ductility index to evaluate ductility capacity of structure and shear destruction ratio, 2) the method can be used to classify the existing buildings either as safe or unsafe, indicating that building might suffer no severe damage or life safety performance level would not be met, respectively.
