Abstract
A routine inspection of the B1 bridge at the Altstädter Bahnhof in Brandenburg an der Havel in December 2019 revealed mas-sive and rapidly progressing damage. The cause of the cracks along the longitudinal girders was suspected to be the failure of a significant portion of the prestressing wires of the concen-trated tendons. The bridge was immediately closed to traffic and demolished in May 2021. Prior to the demolition, the Feder-al Ministry for Digital and Transport (BMDV) initiated further in-vestigations into the damage pattern, which were coordinated and integrated into the deconstruction process by the Landes-betrieb Straßenwesen Brandenburg. The test concept was de-veloped by the Hochschule für Technik und Wirtschaft Dresden(HTW) and is described in the previous article (Part 1). The article at present (Part 2) describes selected results of the ex-tensive measurement and monitoring measures accompanying the tests. The Tests were carried out in cooperation with the HTW Dresden, Bilfinger Noell GmbH and the Bundesanstalt für Materialforschung und -prüfung (BAM).
