【 摘 要 】

Abstract This study proposes a method to evaluate the collapse limit displacement of reinforced concrete buildings based on the seismic response spectrum as a more practical alternative to previous methods based on dynamic analysis. The collapse limit displacement estimated by the proposed method is compared to that obtained by dynamic analysis‐based methods using artificial and observed ground motions. The results of the proposed method correspond well to the dynamic analysis results. However, models with a natural vibration period of 0.2 s exhibited a large dispersion in the results.
