The footing slab of the 40-ft underground concrete tank I am working on will need to withstand uplift pressure (almost 35'). It does act as a ballast. Can I do 90' x60' x 12' thick slab in one pour with no joints assuming the contractor can do it..?
ACI 224 talks about 24 to 36 times the slab...
Can you count the flexural reinforcement across a wall construction joint in calculating the shear friction reinforcement needed to transfer the shear into the footing..? ACI 318 is not clear on that..!
I am working a 40'-deep underground rectangular concrete tank. Due to soil and Hydrostatic pressure loading, the wall thickness is becoming over 5 feet near the bottom. Any ideas to reduce the wall thickness..?
Can I use additional vertical reinforcement to help withstand the shear...?
Thank You.
