BOX-GIRDER BRIDGE ANALYSIS: A MODEL STUDY

Experimentally determined responses of plexiglass models of steel two- and three-girder box-girder bridges with various support skew angles under static live-load conditions are compared with a theoretical analysis representing the structure as a planar grid. The model structures evaluated were small, having span lengths less than 10 ft. Test measurements consisted of strains and deflections. The results show that the planar-grid analysis with properly specified member properties is a reliable analytical tool for checking box-girder bridge designs. Theoretical values are shown to be conservative and adequately to predict transverse distributions of the loads. /FHWA/
