At 2:12 2.65+.15 should be 2.8m, not 2.68. Thanks for the effort. Also, I was curious why u have used 2.8 for max bending moment calculation 9:18 , and then 2.68 for the weight of the walls 15:24 and weight of the soil projection 16:05 .

Very good video Dr. Saleema. I was wondering if you could please do the same example for a larger tank that has columns and beams, i.e. size 170m x 110m x 8m deep with water table 5m above base slab. STAAD Pro demonstration will be greatly appreciated, using ACI codes please. Thanks and best regards

Dear Dr. Saleema.. I believe we should not use the equation of (fs=Ma/(As(d-a/2)) to get steel stress, since the equivalent neutral axis depth (a) corresponds to the strength level loads not the service level loads. May be we use the 0.6fy value. otherwise, fs=Ma*yc/I where yc is the transformed section neutral axis depth. & I is cracked section inertia

Why is the roof slab live load this small considering the tank is underground with unrestricted access by people and equipment? The chosen figure appears applicable to overhead tank.

I think there is a typo fixed at the beginning but used later, the H=2.65+0.15 =2.80m, but typed as 2.68m, and then used later as 2.68m.. Or I am missing something?

@billyjoebreakfast59224 жыл бұрын
Good day!, Thanks, Dr. Saleema for your efforts and granting my request. However, based on the presentation the seismic effect did not consider or since this is below ground level seismic effect is minimal?
@SaleemaPanda19904 жыл бұрын
We can not predict like that. We have to analyze for the same. I can add a video on seismic analysis of water tank.

You can guess the thickness at start and then check if crack width is within permissible else increases your thickness.
@SaleemaPanda19904 жыл бұрын
It's better to have lesser dimension steel bar- then for same amount of steel required, you have more number of bars with less spacing which is good to control shrinkage and cracks.

No only when the uplift force is greater than the downward force acting on the base of the tank.
