Abstract: It is common practice to construct a pier-cap beam integrally with a box girder bridge. Any loading which causes flexure in the cap beam also causes twisting of the box girder. The torsion in the box girder tends to reduce the bending moments in the pier-cap and the piers. The objective herein is to present an analytic procedure which accounts rationally for this interaction and is easily applied in design.
