DESIGN GUIDELINES FOR ELASTOMERIC BEARINGS

Elastomeric bearings shall consist of either plain elastomeric pads or steel-reinforced laminated pads. The bearings may be designed by either Method A (Article 14.7.6) or Method B (Article 14.7.5) of the AASHTO LRFD Bridge Design Specifications. Method A is the required design procedure for plain elastomeric pads.[PDF]
