Various Types of Bearing in Bridge
Various Types of Bearing in Bridge
(OP)
I have a bridge rehab project where we are widening the bridge and adding beam lines. Typically on projects like this if the existing bridge is in good shape, the DOT requests we replace the deck and reuse the old I-beam superstructure making repairs as necessary. Our bearing assemblies for the new beams are a reinforced elastomeric pad. To save money, the DOT wants us to keep the old roller rocker type bearings in the adjacent, original, beam lines. Should I be worried about any differential vertical or horizontal displacement (due to creep, shrinkage, temperature forces, etc.) in the steel vs. elastomeric bearing assemblies? I don't want any longitudinal cracking in the deck.

From previous experience they observed performance issues between with mixing different bearings and were concerned with deck cracking. The stringers are straight, no skew.
