Allowable Masonry Shear Stress

Allowable Masonry Shear Stress

Allowable Masonry Shear Stress

(OP)
What would the allowable shear stress be for an un-reinforced masonry wall that is loaded out-of-plane?  Seciton 2.2.5.2 of ACI530 applies to in-plane shear stress (i.e. shear walls).
Would 2.3.5.2.2 of ACI be applicable even though this section is for reinforced masonry?

Thanks for your input.  

RE: Allowable Masonry Shear Stress

Look at the commentary for section 2.2.5.  They indicate that for out of plane shear the requirements of 2.2.5.2 be used.

RE: Allowable Masonry Shear Stress

I would use caution when using ACI 530 for in-plane shear capacities of plain masonry.  I attended a seminar recently where testing was done on partially grouted walls and the code was considerably unconservative for this case.  It really wants to be ratio'd by Anet/Agross.  The testing done for the code equations was on small walls.  The testing done for the seminar I attended was done on larger scale walls with partial grouting and the wall tended to act more like a frame than a wall.
This will likely be in the code in '11.
