Modeling of Raft

[kyp321]

Hi,

I am modeling a raft  foundation in robot using non linear springs and my model will not converge... I have set a spring limit of 700kN and have checked my vertical equilibrium! Also, I have tried to run a model without limits but it will still not work! Can you help me ?

I am trying to simulate the effect of ground anchors tension capacity (when spring graph is positive) and the bearing pressure of the soil (when spring graph negative).

The results I am trying to achieve are :

1) maximum load on anchor supports 

2) the redistributed moment in the slab given the anchor displacements.

Regards
