we are designing a Pile cap using the STAAD advanced foundation by creating a mat foundation with piles below it.
we are using mat foundation since we want to design combined pile cap for two columns.
while we are doing like this, we found the pile reaction coming in piles below the mat foundation are not same.
it is giving higher force in the central pile and very less forces in the outer piles.
refer attached staad foundation file with mat foundation.
how to resolve the forces?
when we do the same arrangement with pile cap option in STAAD advanced foundation the forces are distributing evenly.
