I have designed isolated foundation in staad ,
The sizing of foundation is coming very high , eventhough my foundation pressure is very less ie) 40 kN/m2 , allowable is 200 kN/m2.
In-terms of sliding and overturning , i am getting minimum of 3.02 ratio.
Can u please suggestion on it , why i am getting more size.
I am attaching my staad file along with this Master.xmlMaster.sfa
