Effect of Concrete Slab Thicknesses to the Deflection of a Composite I-Steel Long Span Girder Validated with Bridge Loading Test Results

Article Preview

Abstract:

Long-span bridges are generally often needed in the world of civil engineering to reduce the number of the bridge piers. A long span steel box girders with a mid-span of 120-meter and two side-spans of 70-meter is studied. The static bridge deflection needs to be evaluated as the constructed slab thicknesses of the steel I-girder composite slab was not constant along the bridge longitudinal span. Results from numerical simulation with those of loading tests carried out on the bridge after its completion are compared.
