Masonry Shear Wall Horizontal Reinforcements

Masonry Shear Wall Horizontal Reinforcements

(OP)
Hello everyone,

The section 21.9.2.2 of ACI 318 dictates "At least two curtains of reinforcement shall be used in a wall if a [factored shear demand] exceeds 2Acv(lamda)sqrt(f'c)." This obviously applies to concrete shear wall designs.

Is there a similar limitation to masonry shear wall designs?

Thank you in advance.

RE: Masonry Shear Wall Horizontal Reinforcements

There sure is. Check out ACI 530/TMS 402 for the requirements.

@mike20793, I read through the MSJC-2011 chapter 3, but I couldn't find the section. Am I looking at the wrong area?

RE: Masonry Shear Wall Horizontal Reinforcements

In the 2011 version, the seismic requirements are outlined in Section 1.18.
