Title: Effects of Longitudinal Forces on Portal Frame Supporting a Highway Bridge Deck

Abstract:Longitudinal forces resulting from live load on a highway bridge deck and from bearing friction at supports of bridge girders produce shear, bending, and torsion in the supporting pier. Messrs. Au and Fok analyze a type of pier often used in highway bridges, namely the portal frame fixed at supports, subject to such forces. Loading is assumed unsymmetrical with respect to the center line of the portal frame. Analysis by moment distribution is extended to include the effects of torsion. The advantages and limitations of the method of analysis are discussed, and the solution for frames with prismatic members is formulated.
