QUESTION--ORE D 101--MEASUREMENT OF THERMAL EFFECTS ON TRACK AND STRUCTURE IN THE CASE OF A DB STEEL BOX-GIRDER BRIDGE WITH CONTINUOUS BALLAST BED (ADDITIONS AND CONCLUSIONS)

This report contains the additional results to RP 18 and concerns measurements taken continuously over a whole year on a 139 m long continuous box-section steel bridge. The track consists of S 54 rails on timber sleepers, laid on continuous ballast bed 34 cm deep (under the sleeper soffit). There are no expansion joints in the track. In the measuring zone the rails were cut about 100 m on either side of the bridge at low temperatures and disconnected from the sleepers. This report describes the time-dependent temperature fluctuations of the rails and of the deck and their effect on the relative displacements of the deck and of the track and also the longitudinal forces in the rails.
