Minimum transverse spacing of WWR in the Diaphragm (ACI)

Minimum transverse spacing of WWR in the Diaphragm (ACI)

Minimum transverse spacing of WWR in the Diaphragm (ACI)

(OP)

Hi!

I read this in the paper:
The ACI 318-99 required using a lower shear strength factor and a larger minimum transverse spacing of
topping wire (10 in.)
to ensure more deformation capacity across the joints in the diaphragm.
[precast concrete double tee flange joint]

Is this 10" spacing still mentioned in the current ACI?
If it is included, where can I see this?

Thanks!

RE: Minimum transverse spacing of WWR in the Diaphragm (ACI)

Can you provide a link to the paper that you ready?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

KootK,

You can see this in

Thanks!
