非線形構造解析によるRC構造物の即時地震損傷度判定法に関する一考察

抄録

This paper discusses the quick inspection technique for earthquake damaged railway bridges using vibration measurement and new numerical model for nonlinear analysis of structures. The accuracy of the Applied Element Method (AEM), used in this study, is verified by comparing with the experimental result of change of natural frequency of the RC column due to damage and also actual earthquake damage to existing two-storied RC rigid frame viaduct. Next, the methodology to obtain the relation between the change in natural frequency and damage levels of real structures is discussed.
