Abstract

Considerable damages and casualties due to the great earthquake such as Northridge(1994), Kobe(1995), Sichuan(2009) and Haiti(2010) earthquake is occurred. Especially, during the earthquake the collapse of school buildings which had done an important role as temporary evacuation of facilities and local disaster prevention center has leading to as a young life. Because of the lack of interest about seismic design and minor earthquake damage of buildings, our country had established seismic design standard not until 1988 year. Considering those circumstance at that time, the standard was limited seismic design respectively for the buildings that over 6 story and total floor area 10,000m2 or important buildings which is national security and public welfare. After repeated revisions, KBC2005 which was based on IBC2000 suggested seismic design standard for building design. However, structures which are under 5 story middle and low-rise buildings was built before the seismic design standard established has not been done and also for school and government buildings seismic design has not been done.

For personal protection and disaster mitigation, it is necessary ensure functionality as a evacuation refuge in disaster. Therefore, the main purpose of this study is that seismic diagnosis of existing steel structure of japan and applicability of performance evaluation method of the United States introduce, we obtain basic information for seismic measure of steel structure in our country. In this study, our goal is that Gymnasium Structure which representative still structure that expect to important roll as refuge and evacuation shelter when disaster is coming down evaluate seismic performance using two different seismic diagnosis, the structure that get a seismic performance rejection evaluate the safety to give a suggest by reinforced method.
