• Abstract:
  Presented are alternate designs for two existing bridges in Virginia - one with steel beams and the other with prestressed concrete beams - whereby the pier caps are recessed within the depth of the longitudinal beams. The purpose of this recession is to provide cleaner aesthetic lines for these bridges. At the same time, the recessed caps (transverse girders) are designed to "float '' or slide on TFE bearings fixed to the tops of the piers. This arrangement allows the number of bearings needed to be greatly reduced. Design calculations and drawings prepared for each bridge permit an economic comparison to be made between the original designs and the. modified designs. The conclusion reached is that the alternate design is completely feasible for the steel bridge; but for the concrete bridge, the alternate design would be more expensive.
