Subject: Question on point of fixity
Fellow Structural Engineers:
In doing a STAAD MODEL for a concrete pile cap supported by a Piles (i.e. concrete or steel); Is there a rule of thumb or guidelines on where we can based the Point of fixity below the mud line for an offshore or onshore projects?
Currently, we used two variables (i.e. 10 x diameter and 8 x diameter) but like to get a second or third opinion.
Appreciate any comments and help.
