Some design aspects of a 215 metre span prestressed concrete box girder bridge

The Queensland Main Roads Department is the design and construction authority for a central city bypass project in Brisbane. A major component of the project is the new farm bridge. This bridge will be of balanced cantilever construction, some 608 m (2,000 ft) long, with a 215 m (705 ft) main span for navigable river clearance. The bridge centre line lies on a 2,300 m (7,500 ft) radius horizontal curve, and is generally 20.1 M (65.9 Ft) wide except toward the southern end where it widens by 2.5 M (8.2 Ft). It will be of precast segmental construction, each 3 m (9.8 Ft) length of box being lifted in two halves. This paper describes the selection of the articulation, longitudinal profile, the transverse bending analysis of the superstructure, and the main pier analysis where the webs are 12 m (40 ft) deep (a).
