Under what situation should engineers use pot bearings instead of elastomeric
bearings?

1 Answer

Answer :

In the event of high vertical loads combined with large angle of rotations, rubber bearings are   undesirable   when   compared   with   pot   bearings.   For   instance,   elastomeric   bearings require large bearing surfaces so that compression can be maintained between the contact surfaces between the bearings and piers. Moreover, it also leads to uneven distribution of stress on the piers  and some of these highly induced  stresses may damage  the piers. Consequently, pot bearings are better alternatives than elastomeric bearings in such an scenario as suggested by David J. Lee.
