Bond Beam Spacing

[jwright81]

Does anyone know where to find the min interval spacing for bond beams in CMU blocks? Any help would be appreciated.

(I have a feeling it is in the masonry code--but where??)

There is no minimum that I know of for running bond. For stacked bond, see ACI 530 (02) section 1.11.

 

[STR04]

It depends on what Seismic Design Category you are in. For D and above the code required .002bh with maximum reinforcing spacing not to exceed 48" ea. direction. See 1.13.6

Someone designing in Florida here can verify this but I believe there is a 10ft spacing limit for South Florida. And like STR04 was saying that for SDC D and worse I have often seen bond beams placed at 4ft to satisfy the minimum horizontal requirement.

When things are steep, remember to stay level-headed.
