Earthquake is one of the hazard so hard to provide because it is difficult predicted occurred time, scale and characters. Neighbors which have damaged by earthquake look out for statement of damage, It is bigger than nation which has not prepared seismic code at ordinary time seismic damage which belong to loss of life. The earthquake in Kobe, Japan showed that the damages were concentrated on the buildings which were not considered to be protected from the earthquakes. Seismic code applied structures was small damaged but non applied structures was much damaged such as collapse and loss of life. In this study, apartment structures in Korea analyze about earthquake hazard and evaluate seismic performance. Through the this study we have notice of earthquake hazard for apartment structures which live a lot of population of Korea and suppose necessary for seismic retrofit.
