bond beam spacing
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??)
check out our whitepaper library.
there is no minimum that i know of for running bond. for stacked bond, see aci 530 (02) section 1.11.
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.
