Dear hakan,
have a good day
while analysis the attached building having single foundation, and the allowable bearing stress for soil was 100 kn/m2,
i got the negative stress and didn't check for bearing soil...Even if it did not check positive less than the allowable.

Hi Ammer,

You may define single footing as symmetrical. Non symmetrical single footing's eccentricity causes negative soil stresses.

See sample project that I enclosed to topic.
 
thanks hakan to this clarification,
but in my case i can not do it because of the boundary are limit and not allowed to out extension,and may be solve by mat foundation,but i want to see how idecad deal with negative stress.
thanks again :D :D :D
