What LRFD resistance factors should be used based on AASHTO Table 10.5.5.2.3-1 for axial resistance of pile computed through different methods (API, FHWA, USACE) from APILE? APILE manuals are a bit vague and don't offer much insight into it. Thanks in advance.
While modeling the group of piles in Ensoft Group Pile software, do we need to add the dead load of pile cap into the axial load input or is that calculated by the program based on pile cap dimensions we provide?
