Abstract

Recent earthquake in Japan has increased the interest in seismic-resistance performance of building structures in Korea. Earthquake damages not only collapsed the buildings but also caused huge loss of both human lives and property. Therefore, the school buildings, which are often used as an emergency shelter during an earthquake, should be evaluated of their seismic-resistance performance. This study used a nonlinear dynamic analysis program, OpenSees, to perform nonlinear static and dynamic analyses for the seismic-resistance evaluation of school building, which were not designed for an earthquake load. Actual earthquake waves were normalized to make them similar to design acceleration spectrum as specified by current seismic design code KBC 2009. Three actual ground accelerations (i.e., El Centro 1940, Kobe 1995 and Northridge 1994) were used to carry out time-history analysis in order to evaluate the overall behavior of the structure and local nonlinear deformation at the element level. The analysis result shows that the old school building not designed for an earthquake may be damaged seriously by an earthquake load of the magnitude equivalent to current design spectrum standard.
