2500# is for the soil below the limestone.
The limestone is a packed about 9" on top of the soil.
The plan is for the footing to be on top of the limestone to avoid digging into the limestone.
Yes, you are correct jike. I defintely need more weight.
Let me run this by you to make sure I understood correctly:
I would need a total of 200k of concrete with a F.S. of 1.5.
[1.5 X 167K = (50K + Xk); where X = concrete weight]
So, based on that, if I were in the ground (vs being ontop)I...
Thank you all for your recommendations and suggestions.
My footing depth is not really limited other then I don't want to go too high. My footing is above ground on top of limestone. I have a pedestal that is 3'x3'x18" (my base plate is 2.5'x2.5'.) Which makes it already 3' above the ground...
I would like to know if I can use steel beams instead of rebar for my reinforcement in my concrete footing.
I have a 15'x15'x19" footing and since I have compressive and uplift forces I need to doubly reinforce my footing (top and bottom). However, based on my calculations I need a lot of...
