DESIGN OF CONTINUOUS HIGHWAY BRIDGES WITH PRECAST ...

Continuous highway bridges with precast, prestressed girders have been built by a number of states. Examples of bridges of this type built by the states of Tennessee and California are presented in Figs. 1 and 2, respectively. The Big Sandy River Bridges in Tennessee were built in 1963-64. Performance has been excellent. The 639-ft. and 703-ft ...

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.

The precast, prestressed concrete form panels are not continuous over the bridge beams as illustrated by the cast-in-place concrete between the ends of the panels 6. At the outside edges of the bridge 7, the form panels are usually cantilevered over the beam to support a portion of the deck slab and the cast-in-place parapet 4.

The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.
