360369 A SIMPLE IDENTIFICATION METHOD FOR MEMBER VIBRATION PROPERTIES OF RAILWAY VIADUCTS(Condition Monitoring,Technical Session)

Abstract

For train speed-up, resonance response of structures and these environmental performance of it such as ground vibration and noise are critical issues from the viewpoints of safety and serviceability, respectively. To adequately tackle these issues, the vibration properties of structures must be thoroughly understood on an each member. In this study, we estimated the vibration mode shape and the natural frequency of RC rigid frame railway viaducts based on results of simultaneous multipoint measurement and proposed an estimation method for member vibration.
