POT Bearings for Steel B

[Subject Prev][Subject Next][Thread Prev][Thread Next]

POT bearings are generally proprietary and capacities are based on the way 
they are manufactured, taking into consideration confinement of the 
elastomeric material, thickness, etc.

I would select and specify one or several manufacturers as acceptable.  A 
major consideration is the size of the bearing and skew of the bridge which 
will determine the minimum width of your pier/abutment seat.
