I have a pier foundation that I would like to analyze against axial plus lateral load. I see two options in STAAD Foundation for drilled piers, one in toolkit mode and the other within Plant Mode. Which one should I use ?
The one within the Toolkit mode is only for axial loads. The Drilled/Driven pier option within the Plant mode is equipped to carry out analysis of piers with axial and lateral loads and should be the one used in this case.
