BRAKING AND ACCELERATION FORCES ON BRIDGES AND INTERACTION BETWEEN TRACK AND STRUCTURE. BRAKING FORCES ON A PRESTRESSED REINFORCED CONCRETE BRIDGE WITH NEOPRENE BEARINGS

The report gives results of braking effort measurements on a pre-stressed concrete railway bridge with 21.5 m span, with continuous ballast bed. Part of the tests were made on the bridge supported by steel bearings, the other part on the same bridge with neoprene bearings and the results were compared. The distribution of braking effort into the bridge abutments and rails were measured in the study with a short and a long train. The large influence of the neoprene bearings, which cause forces in rails to be increased, is significant.
