Modelling foundation piles in SAP2000

[james37]

Hi everyone,

I have a building project in hands in which is required to simulate several foundations conditions:

1 - Foundation slab among piles;

2 - Only Piles.

My doubdt relies on the the best way to simulate those referred piles. Until now i'm modelling the piles "only", by assigning "winkler" springs. Is it the correct way?

I'm also asking this, because, in the reality those piles might get to its stress limits and, in that case part of the loading goes to the slab. That's why i'm not sure if the way i'm simulating is the correct way.

The only data received from the foundations team (it is another company) is the pile stifness and its strees capacity.

Thank you,

SAP2000 is not geotechnical software, SAP2000 is software for structure.
in my experience related work with structural engineer they only calculation for super structure, for foundation always handle by geotech engineer.

for medelling pile if you already have calcultaion working load for all coloumn (axial, shear, and moment) in SAP2000, you can modelling pile use geotechnical software like Plaxis, Geo5, AllPile, etc..

I believe you can have a good idea using the sap, as you've got the pile stiffness you can model the piles as springs and then you can judge the simulation through the resulting settelment, if it is within the allowable values or otherwise you need a new iteration using new arrangment of piles or stiffness
