Abstract:     
 
Der Rückbau von Talbrücken in beengten Tälern oder in unmittelbarer Nähe zu unter Verkehr stehenden Überbauten erfordert neue Konzepte für den ingenieurmäßigen Rückbau. Analog zum Neubau müssen die Rückbauzustände ingenieurmäßig untersucht und die Standsicherheit nachgewiesen werden. Für Bauingenieure ergeben sich hier neue Herausforderungen, die innovative Lösungsansätze und kombinierte Nachweise aus rechnerischen und experimentellen Untersuchungen verlangen.

Structural engineering in dismantling of concrete bridges
The deconstruction of viaducts in constricted valleys or in immediate vicinity of superstructures under traffic requires new engineer concept for the dismantling. Analog to new bridges the structural stability has to be proven for all states of deconstruction. This results in new challenges for civil engineers with innovative approaches and combined proofs with numerical and experimental investigations.
