WALL MINIMUM SHEAR REINFORCEMENT
WALL MINIMUM SHEAR REINFORCEMENT
(OP)
I am designing a restrained retaining wall, the out of plane shear, Vu, due to soil lateral load, are more than 2x larger than Phi*Vc, in other words -
Vu > Phi*Vc/2
Per ACI 11.5.5.1, minmum shear reinforcement is not required in slabs, footings, or beams with total depth note greater than 10", 2.5xthickness of flanges, or 0.5xwidth of web, ...
How about wall? Since I am designing the retaining wall as flexural beam behavior, and if the wall thickness is less than 10", it should not be bound by ACI 11.5.5.1 - Minimum shear Reinforcement, is this correct?
I would really appreciate your valuable input on this. I hope you could shed somelights to this matter.
Thank you in advance.

Section 14.3 and 11.10

RE: WALL MINIMUM SHEAR REINFORCEMENT
Per 11.10.1, shear perpendicular to wall is similar to slab design because out of plane shear is beam action, which refers to 11.12.
11.12 refers back to 11.1 thru 11.5
11.5.5.1 specifies minmum shear reinforcement is NOT required in slabs, footings, or beams with total depth note greater than 10", 2.5xthickness of flanges, or 0.5xwidth of web, ...
My understanding is out of plane shear is a beam action, so, if the wall thickness is less than 10", then it is not entitled to minimum reinf.
Please correct me if I am wrong
Thanks

Scottiesei, I thought 14.3.1 to 14.3.3 is addressing in plan shear.
For out of plane shear, the shear reinforcement is cross ties. Please correct me if I am wrong.
