COMPOSITE BOX GIRDER BRIDGES -- THE CONSTRUCTION PHASE

A series of scale model studies of simple span torsionally open and quasi-closed have been undertaken to examine the effects of representative construction loadings on the overall stability and deformations of single and interconnected box girder bridges. In addition, the forces in various types of bracing located within and between trapezoidal box girders have been measured. The models had scales of 1/20 and 1/4, and are considered representative of typical prototype bridge systems. A review of various types of construction loadings is given for design use. The model studies indicate that nominal bracing within and between trapezoidal box girders is essential if the sectional shape and member alignment are to be maintained during construction. Bracing configurations for the construction stage are discussed. 17 refs
