Maximum rebar spacing in CMU wall
Maximum rebar spacing in CMU wall
(OP)
My understanding is that some, but not all, codes limit the maximum spacing of vertical rebar in CMU walls to 48". ACI 530 has limits on the effective width to be used for compressive stress (least of bar spacing, 6 times wall thick, or 72"), but nothing with regards to flexural design. Can anyone direct me to applicable sections where rebar spacing limits are discussed?

Take a look at the download "Test Report-Effective Width "b"" avaible from Masonry Institute of America at:

It's an oldy but a goody. There are several other good downloads from this site as well.
Ultimate strength design does, however, have some reinforcement limits that may restrict bar spacing.
