ABSTRACT
ABSTRACT: Some experiences and studies on the subject of track-bridge interaction in Japan are presented. As for the problems in ordinary conditions, studies on the influence of the temperature change between CWR and bridge girders, experiences on the vibration isolation using a newly developed track system, and experiences on the rail extension and contraction at edges of a long span bridge are introduced. As for the problems in seismic conditions, studies and experiences on the vehicle’s running safety on structures, and displacement limit criteria of track and structures are introduced with some explanation on a vehicle/track/structure interaction analysis program.
