Horizontal Reinforc'g in Masonry Walls

Horizontal Reinforc'g in Masonry Walls

Horizontal Reinforc'g in Masonry Walls

(OP)
Are the requirements for the minimum horizontal steel (0.007Ag)in a masonry wall for wind design the same as for seismic loading.  I looking at a masonry wall in 130-mph wind speed.

RE: Horizontal Reinforc'g in Masonry Walls

Looks like your wind pressure would generates a reaction high enough to push you beyond the minimum requirement, unless you stick to one way design.

RE: Horizontal Reinforc'g in Masonry Walls

I am curious as to which code requires .007Ag horizontal reinforement in masonry walls.  That is a lot of reinforcement, and it must be for seismic loading.  Wind loading normal to walls is usually taken by one way bending between floors, with only a nominal amount of horizontal reinforcing.  A greater amount of horizontal reinforcement is often required in shear walls of multistorey buildings, but that doesn't come under "minimum requirements".  

RE: Horizontal Reinforc'g in Masonry Walls

There's a digit missing in the number. It's .0007Ag for Seismic Class D and above in ACI 530-02 1.13.5

RE: Horizontal Reinforc'g in Masonry Walls

In that case, that is not much reinforcement, but is about twice the amount some codes prescribe for "secondary reinforcement" in reinforced masonry.
