Almost low-rise reinforced concrete school structures are not applied in the seismic codes of Korea and seismic risks of existing reinforced concrete building are enlarging in Korea. Therefore, We have to provide effective earthquake preparedness against future earthquake to avoid a large seismic damage. For this reason, this paper has developed estimation method of seismic capacity for low-rise existing RC school structures.
In this study, domestic and the other country's codes for estimation method of seismic capacity of existing RC school structure are briefly summarized and damaged school structures due to severe earthquake in Japan are examined. then, the feature of damaged school structures are analyzed for applying existing estimation method of seismic capacity.
As the results, we proposed the new estimation method of seismic capacity through multiplying ductility index by first estimation index of seismic capacity, and the proposed estimation method is proved adequacy comparing to second estimation index of seismic capacity
