The Bridge BE 109/21 in Bützberg/BE, Switzerland, was built in 1970 as a part of the railway route between Bern and Zürich. Recently the bridge was demolished because of changes in SBB the railway routing (Bahn 2000). As a part of the SBB initiated research program “ZEBRA” the load capacity of the bearings will be investigated within labor experiments. In order to collect data about the behavior of the bearings dependent on temperature influences, two monitoring periods measuring the deformations of the bearings and the temperature of the superstructure during the summer- and winter time were performed.
