A Rentangular Tanks Design - Rebar for direct tension in wall
A Rentangular Tanks Design - Rebar for direct tension in wall
(OP)
Hello
Another simple question that I wonder is
PCA Example No.1 they mentioned about "Steel required for direct tension in long wall"
Steel required : [A][/s]=[N][/u]/(0.9 X [f][/y])
Where does this formula come from?
I've found "ACI 350-06 Clause 11.7.4 Shear-friction design method"
Those two are similiar but not same.
Would you give me a reference for the PCA design?

Just make sure Nu has all the proper factors on it and your laps are conservative.

Anyone have the PCA on pdf?

I agreed with your reply. However, I found a similar formula that could be used in this case.
If you have ACI 350 then look into Clause 11.7.4(Shear-friction design method).
ACI 318 - 11.6.4(Shear-friction design method).
But there is "mu - coefficient of friction".
So I'd like to re-ask you whether this section(clause) could be applied to my case.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

Thanks and I agree with you.
But would you tell me some reference for direct tension
Of course that formula can be derivated from simple engineering thought
"Tension will be resisted by reinforcement."
But there's a phi factor and I can't find reference.
And do you ageee with that direct tension should be considered in this
Tank wall design?
To sum up
1. Reference for the PCA FORMULA for the Direct tension?
2. Should Direct tension be applied to tank wall design?

Thanks! I'll look through it.
