A p-version, two-dimensional (2D) finite-element model incorporating both material and geometric nonlinearities and a consistent frictional contact algorithm is utilized to analyze elastomeric bridge bearings. Stresses and strains are examined and factors affecting them are discussed. In particular, tapered bearings, used to support inclined girders, are analyzed. The shear stiffness of both flat and tapered pads is investigated. It is shown that deforming a tapered pad vertically results in a horizontal reaction that should be considered for proper bearing design. Comparisons with some recent experimental findings are shown.
