Hi everyone:
during my design of a foundation with high eccentricity ( eccentricity out of middle third ). I tried to calculate soil pressure manually and then by SAFE software. But I couldn't justify the large difference in soil stress results. I have attached a PDF file showing the two results. can anyone share his/here thought about this discrepancy?
where thickness of footing = 200 mm
modulus of subgrade reaction = 18000 kN/m3 ( calculated based on allowed settlement = 8.33 mm )
allowable bearing capacity = 150 kN/m2
width of footing = 0.8 m
length of footing = 1.95 m
total service load = 51.6 kN
total service moment = 40 kN.m
thanks.

While it is semi-structural it is really dealing more with a foundation design issue.

but still, if I calculate the center of soil stress it won't coincide with the eccentricity of external applied force. does anyone know the reason ? I've been told that the reason of this: that foundation should be sized in a way prevent any tension at soil i.e. maximum eccentricity should not be out of middle third.
I'm asking why not? does it mean that the footing will undergo excessive rotation in order to meet the large eccentricity ?
