Zur Ortbeton‐Ergänzung einschaliger Halbfertigteilwände

Abstract: Am Institut für Tragkonstruktionen der Technischen Universität Wien wird derzeit an einem neuen Bauverfahren für vorgespannte Hohlkastenbrücken geforscht, wobei dünnwandige Halbfertigteile zum Einsatz kommen, die das Gewicht im Bauzustand erheblich reduzieren. Das geringste Eigengewicht wird bei der Verwendung einschaliger Wände für die Stege des Hohlkastens im Bauzustand erreicht. Diese Arbeit behandelt Untersuchungen zur Ergänzung von solchen einschaligen Halbfertigteilwänden mit Ortbeton, wobei drei Lösungs… Show more

“…The implementation of such lightweight structural elements allows for the development of new approaches for the construction of bridges, as was impressively demonstrated when the balanced lowering method [3][4][5] was used to build two bridges over the Lafnitz and Lahnbach Rivers in Austria. Another application concerns the semi-precast segmental bridge construction method [6][7][8], in which thin-walled precast concrete elements are assembled to form a box girder with the aid of steel components.…”
