Many times I saw 1.5" concrete topping over plywood and wood frame called out for townhome or condo. I never saw 5” concrete of (2) cars garage floor over a plywood and wood frame floor. Have anyone ever call out 5” concrete on top plywood and wood frame before?
TIA
Thank you for all responses. The wall was constructed.
I used equivalent active pressure 35psf/ft and 250psf/ft passive pressure.
Since there is lots of room remains in front of the wall, therefore I used 4ft soil to restraint the sliding.
How come there are many Ultra Block walls that...
I have 10' high concrete block 2.5'x2.5'x5' (W,H,L). DL= 3750#/ft
P= .5(.32)110(10)^2 = 1760#
When I check the sliding factor, then I never get the safety value over 1.5.
u = .5;
F = .5 x 3750 = 1875
Sliding factor = 1875 / 1760 = 1.1 Which is less than 1.5
Does anyone know why? or any other...
