BRAKING AND ACCELERATION FORCES ON BRIDGES AND INTERACTION BETWEEN TRACK AND STRUCTURE. STARTING AND BRAKING TESTS ON A REINFORCED CONCRETE THREE-SPAN BRIDGE WITH NEOPRENE BEARINGS

This report presents the results of braking and starting measurements taken on a reinforced concrete hyperstatic three-span bridge consisting of two adjacent but independent 35 m decks, one carrying track laid on the ballast and the other with the track laid direct, with special neoprene bearings. The report describes with the distribution of the braking and starting forces in the abutments, the piers and the rails, with different locations of the fixed bearings and with different continuous and discontinuous rail configurations for each of the two types of deck. It also indicates the measured values of the thrusts transmitted to the ground in the case of the deck with ballasted track.
