RE: Min. masonry reinf

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you are doing the job in California, the inertia is to fully grout the
walls.  If the walls are fully grouted, it does not make much difference on
the distribution of vertical to horizontal rebar.  

If the walls are partially grouted, it is best to space the vertical rebar
out as far as possible without having to go to big bars.

You will also find that it is more economical to eliminate vertical rebar
splices and use "A" block, which is now required on Corps projects.  The "A"
block can be placed around the rebar as opposed to stringing the block over
the top of the bar.

Subject: Min. masonry reinf

I have a 12-inch thick concrete masonry wall to be reinforced per UBC's 
minimum reinforcing requirements for Seismic Zone 3 (i.e., total vert +
reinf greater than 0.002 times gross area of wall).  Any recommendations on 
the most economical arrangement of vertical reinforced cells and horizontal 
bond beams (and/or horizontal joint reinforcement) to satisfy the code?
