In seismic zones 3 and 4, maximum reinforcing spacing is 4 feet (2220.127.116.11.2.2.3).<< But beware of the UBC reinforcing requirements for Seismic Zone 2! These reinforcing requirements are the result of HUD tests for *small* (< 2500 sf), lightly loaded, single story, one- or two-family residences and were somehow extrapolated to be permitted for buildings of *any* occupancy, height, and loading conditions in Seismic Zone 2. >>Bond beams are not specifically required, though. You can use joint reinforcing to satisfy minimum reinforcing requirements.<< If you carefully read brochures for joint reinforcing such as produced by Dur-O-Wal and AA, I think that you will find that joint reinforcing is restricted to crack control usage, and is not authorized to resist stress.
