ACI 318 ordinary shear wall
ACI 318 ordinary shear wall
(OP)
A couple of quick questions.
First, does anyone know of a good example for an ordinary shear wall designed per ACI 318 per section 11.9? I can find a bunch of examples for special shear walls per section 21 for seismic but the only example I can find for an ordinary shear wall is in the 2nd edition of the PCA book "Seismic and Wind Design of Concrete Buildings, 2nd Edition" but that only uses ACI 318-02 and their equations are vastly different than 318-08 and 318-12.
Second, and if an example can't be found, can someone clarify their use of Mu (factored moment). This is used in equation 11-28 in section 11.9.6. I take this to be the factored out-of-plane moment in the shear wall but I question wither they mean the overturning moment in-plane with the shear wall. Can someone clarify this as ACI 318 is extremely unclear on what Mu actually means.

RE: ACI 318 ordinary shear wall
I found an example in "Reinforced Concrete Mechanics and Design, 4th Edition" by MacGregor and Wight. Example 19-14 covers design of a shear wall for wind loads per ACI 318 section 11 and uses up to date equations. Excellent.
It appears, if I read this correctly, that Mu is indeed the in-plane moment on the shear wall. Not the out-of-plane moment that I had previously thought.
