Hello Kris Sathia iam attaching the design report of Staad Advanced and the spreeedsheet which i created to compare the results.
please help me on the issue of sliding for load case 1002 which is critical ,i dont get similar results on my spreedsheet compared to Staad advanced Foundation.
FOOTING SIZING SPREEDSHEET JOSEPH LUCAS MAGARE.xlsx
We differ in governing restoring forces as you can see on spreedsheet my restoring force is 311.918kn but in Staad Advanced is 406.07kn
One of my colleagues who looked into your calculation says that you have not considered the contribution of the passive pressure to the restoring moment.
I have included,this is the summarized one you can see passive is included
Maybe i had to include the passive force in pedestal and footing plus the resisting force?
Let me try to do that and i will give you feedback
Yes your colleague is right,thank you the results are now the same.
I had to defend to my colleague he was trying to reject the footing design which i submitted he was complaining the size of the footing is bigger without giving me concrete evidence,then i had to give him theory behind on manual design to show him that the Staad Advanced Foundation designed correctly and my design is ok considering the size of the footing
Thank you Kris Sathia
