Calculating bearing pressure for foundation with moment load , shallow foundation design Example 4

[@1MehmetAydin]

simple and clear explanation. good job mate

[@p.3914]

Excellent work. Thank you.

[@zinash5mashie993]

Thank you, it is a clear explanation

[@dnecdesignandbuildkonsult7106]

please is it possibly to have another demonstration of this video in metric form....?

[@zayurisatencio4390]

Do we still need eccentricity if we have one load including weight of footing and soil? If so, how would it be?

[@alonzobizahaloni3953]

I would like to know how predict the sinkage of a box on a wet soil. Is there any books out there that I need to read that will help me.

Can you please share where we can reference these formulas and where to reference the relation between B/6 and the distribution shape?

[@mattgerber4849]

I'm not familiar with the above formulas, but they're basically just simple statics equations rewritten. Think of a shallow footing like you'd think about combined axial and bending stresses in a beam: qmin = P/A - M/S qmax = P/A + M/S S = I/y = (bh^3/12)/(h/2) = bh^2/6 = 1*5.5^2/6 = 5.042ft^2 per foot width For your B/6 and distribution shape question, if we have a triangular distribution, qmin = 0. If qmin is greater than 0, we get a trapezoidal pressure distribution, and if qmin is less than 0, part of our footing will not be in compression with the soil. qmin = 0 = P/A - M/S M = P*e, A = bh, and S = bh^2/6, so: P/bh = P*e/(bh^2/6) Solve for e, and you'll find that e = h/6. Hope this helps!

Thank You!

What method is this? Differs from ACI.

[@EngineeringexamplesNet]

This calculation is not dependent on code. It is based on statics.

[@abbzabbz2584]

sir what is the size of the post?

[@abbzabbz2584]

the drawing is not good.what is the size of rhe post? there is 10ft.and 15ft.

imperial??? cant get it.

[@ryanjayimperial5395]

kips is kilopounds only, So why you write 10 kips/ft into 10000 ft-lb/ft. It should be 10000 lb/ft

[@shohel1718]

Where you get 15000 lb/ft

[@mosesasomaning6524]

15 k.ft converted to lb.ft = 15(1000)

[@rosagamarra1171]

what is b?

[@angelomargallegos7856]

1 foot

[@DavidTerryTAEC]

For the e calc the b's all cancel out. I typically see the eccentrically calc'd like: e=M/P. But b is just the footing width, typically.
