model a support with limited load
model a support with limited load
(OP)
Hi,
I have an existing foundation with 6 piles supporting the footing, but the allowable working load of one of these piles is limited to 150kips. But the applied external force is about 180kips on this perticular pile. How I can model this support in SAP2000 with the maximum reaction limit to 150kips?
Thank you in advance.

Hopefully once you sort the first pile out, none of the others will exceed 150kips, otherwise good luck.

Modeling the piles using a pinned restraint gives you the worst case load which is typically the reaction that you would want to use in a new design. Modeling the piles as springs (calculated based on pile section, pile length and soil data) will obviously add some flexibility which may change load distribution.
