Die Verformungsberechnung der Lahntalbrücke Limburg

Abstract

EinleitungDer The deformation calculation of the Lahntalbrücke LimburgThe new Lahntalbrücke in Limburg is a semi-integral prestressed concrete structure that has emerged from a design competition. It is distinguished by its slender, attractive design. The superstructure is currently erected as balanced cantilever construction. Subsequently, the peculiarities of the deformation calculation of the Lahntalbrücke are presented. The considerations about the allocation of the construction sections are discussed. The individual amounts of deflection to be considered are shown and the resulting deformation calculation is explained. Finally, the implementation of the deformation calculation regarding deflection measurements on the construction site is presented.

Criteria and influencing parameters for the design of piers of semi‐integral bridges

“…Because several structural parts take part in carrying the loads, it is also possible to build very slender structures, which are simultaneously stiff and robust . Some semi‐integral railway bridges have been built in the recent past on VDE8 (greatest railway project over the last decades in Germany with 40 viaducts), as well as semi‐integral road bridges are built …”
