a Welded deformed bar mats shall be permitted to be assembled using A615 or A706 deformed bars.<br />

b ASTM A1064 and A1022 are not permitted in special seismic systems where the weld is required to resist stresses in response to confinement, lateral support of longitudinal<br />

bars, shear, or other actions.<br />

c Nonprestressed bars and wires permitted for shear and transverse torsion also apply for special seismic.
