Masonry code confusion 1

[WARose]

I was looking at a (dated by this point) version of ACI 530 I have…..and something that has always bothered me compelled me to post. At one point it says this:

6.2.1 Alternative design of anchored masonry veneer: The alternative design of anchored veneer, which is permitted under Section 1.3, shall satisfy the following conditions……. (d) The veneer is not subject to the flexural tensile stress provisions of Section 2.2.

I’m not sure how to take that. Are they saying the cross section is not to see any (net) tensile stresses (combining flexural with self-weight) if done by the alternative provisions?

If so, there are a lot of cases where the alternative provisions can’t apply (with a typical wind load)....and that is even considering two-way action generating the moments (from the required anchor spacing: one for every 3.5 ft² of wall)

Am I just misinterpreting this or is there something I am missing? Thanks.

I take that section to mean that alternatively designed veneer need not be designed to comply with either the allowable stress nor strength design provisions of the referenced sections. It's basically the wild west and you can do whatever the heck you like. It's a poorly expressed provision in the sense that it's really a permissive clause tucked away in what reads as a restrictive section.

Interesting. They must be counting on clause (b) to hold it together.....and it can crack to hell for all they care. Thanks kootk.
