A box girder bridge is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. Steel box girders and steel and concrete composite box girders are used for long spans, where the self weight of the bridge needs to be minimized, and for situations where their excellent high torsional stiffness is of particular benefit. Shibanpo Bridge Breaks World Record for Longest Box Girder Bridge Span. The entire bridge was built using a cast-in-place concrete free cantilever segmental method, with the exception of a 103m section in the middle of the main span, which is a steel box.
Attached is a model file and a PDF which outlines the procedure for modeling a concrete box-girder bridge, a steel-girder bridge, and a cable-stayed bridge. A computer program for the design and analysis of a prestressed concrete box girder bridge built by the Cantilever method is presented. The method described herein replaces the costly and time-consuming manual calculations with an efficient digital computer program. Concrete Box Girder Bridges J.
