SEGMENTAL AND STAGE CONSTRUCTION OF PRESTRESSED CONCRETE BOX GIRDER BRIDGES

Prestressed Concrete Bridges of uniform or near uniform cross-section are admirably suited to construction by precasting segments and post-tensioning. This form of construction, however, introduces additional design and construction problems--problems of carrying flexure, shear and torsion across joints--the most suitable type of joint,--problems introduced by superelevation and constructional tolerances. As the length of the structure increases, the effective prestress is reduced markedly until it is no longer economical to stress in one operation. The method of stage stressing will overcome these problems, however more complex analysis and design is required. Solutions to these problems are discussed with particular reference to several large prestressed concrete box girder bridges recently constructed in Australia. /Author/
