How to do crack control according to ACI code
How to do crack control according to ACI code
(OP)
Hi all,
This is new engineer design with ACI code.
I am doing a pond design and want to do the crack control.
I see that ACI 350.1 10.6.4.2 has some equations for crack control.
Also I see there's one exception that while the cover is greater than 2 in. mentioned in R10.6.5.
But there's no further how-to-to in ACI 350.1 nor in ACI 318-02.
Currently I am using a cover that is greater than 2 in. so I would like to know which equations I can use for crack control.
Thanks a lot!

RE: How to do crack control according to ACI code
as far as i know, crack control is just a formula that will have more reinforcement and tighter spacing.
RE: How to do crack control according to ACI code
There's formulas to calculate the reinforcement and spacing, but only for structure where the cover is less than 2 in.
Since I am using cover greater than 2 in., I try to find corresponding formulas but I couldn't.

first off, I don't see any R10.6.5 (not used).
I see this on R10.6.4
"The numerical limitations of z = 115 and 95 kips per in. for
normal environmental exposure and severe environmental
exposure respectively correspond to limiting crack widths
of 0.010 and 0.009 in. These z values were established for
cover equal to or less than 2 in. and should be based on this
value even when cover exceeds 2 in. Additional cover may
be regarded as added protection."
it looks more to me the limitation is for 2" cover or less.
don't see anywhere the 10-5 formula is only for 2" cover or less.

There's explanation of the exception in R10.6.5
Thanks.

If you have 2001 version there is no R10.6.5 at all.
