QUESTION: While designing the Pier columns and Drill shaft are all service and strength analysis results given for first order effects only ?

ANSWER:

RC-PIER takes the portions of the drilled shaft below fixity point as a member supported laterally. In this case, only the axial load is considered. For the portion of the drilled shaft above fixity point, RC-PIER assumes there are no lateral supports. Therefore, it is designed exactly the same as a reinforced column, taking into consideration of both axial load and moments.
