No, the pile group (or any foundation for that matter) must be calculated with an R-factor of 1.0 (i.e. elastic) or the plastic moments generated by the column(s), whichever is smaller. This is based on the capacity design approach, where it is assumed that you'll hit one of...
Kokonis36,
Two comments on your question:
1) Fundamentally, bridge design follows the weak column/strong beam concept (basically opposite of buildings.) Because of this, the superstructure (bridge deck) is a capacity protected element and must be able to behave elastically under plastic...
