Precast posttensioned abutment system and precast superstructure for rapid on-site construction Scanlon, Andrew ; Aswad, Alex ; Stellar, James
Utgivningsinformation: Transportation Research Record, 2002Beskrivning: nr 1814, s. 65-71Ämnen: Bibl.nr: VTI P8167:1814Location: Abstrakt: A prefabricated bridge system was designed to minimize on-site construction time. The system consists of a double-cell adjacent box beam superstructure supported on precast posttensioned abutment units on cast-in-place footings. The design concept was implemented in a demonstration bridge replacement project, a single-span bridge crossing a creek in southwestern Pennsylvania. The construction project demonstrated the feasibility of the design concept as a means to reduce construction time by eliminating cast-in-place concrete for abutment walls.| Omslagsbild | Exemplartyp | Aktuellt bibliotek | Hembibliotek | Avdelning | Hyllplacering | Hyllsignatur | Specificerade material | Volyminfo | URL | Ex.nummer | Status | Kommentarer | Förfallodatum | Streckkod | Exemplarreservationer | Köplats för exemplarreservation | Kurslistor | |
