限界耐力計算とINTERNATIONAL BUILDING CODEの耐震規定により定まる建物要求耐力の比較と検討

抄録

This paper compares and investigates the relationship between required strength and response ductility of the seismic design codes of International Building Code used in the U.S., and Calculation of Response and Limit Strength used in Japan. Based on dynamic theory, the paper also proposes the rational modification for International Building Code for two patterns of yield drift angle models which significantly affect on the dynamic response of the buildings. The modified International Building Code shows excellent correspondence to Calculation of Response and Limit Strength.
