Hello sir I am your big fan i regularly watch your vid plszz make vid on staad pro like warehouse design, pipe rack design , admin building, workshop, compressor house etc .. plszz make vid on this topic
While calculating moment why there is difference by Manual calculation and through excel sheet . In excel sheet ur talking average of stress … in manual calculation u calculate stress due to moment while neglecting stress due to another axial moment .
My comments on how you get your bemding moment, your pressure is not linear so you can create a diagram like for example shear and moment diagran then from there you can calculate for the moment at the face of the column. Also in you 3 columns in mat footing your moment there is wL^2/8 where we know it is not because it cant be a simply supported. We should not also averaging the stress.
The footing is useful for small loaf. Ok. In your case the load consider is 13 KN. Why so much less load is consider.Also you simply the case by neglecting moment Mx and Mz.
That’s what I am saying. Such footings shall be avoided unless the load is very small and moments are negligible such that it doesn’t alter the bearing pressure.

Dear sir,

Sir How can I get this Excel sheet
From etabs we will get ultimate load but here u have taken it to be service load why and how
