Code Update:ACI 318:High-Strength Reinforcing Bars

Aug 23, 2017 · Only Grade 60 steel reinforcement is permitted in ACI 318-14 for use in special seismic systems (special moment frames, special structural walls and all components of special structural walls, including coupling beams and wall piers) to resist the effects caused by flexure, axial force, and shrinkage and temperature. Considerations for Use of HSS in Seismic Frame Systems For the seismic frames shown in Figure 1, square, rectangular, and circular HSS are limited to ASTM A500 Grade B, ASTM A500 Grade C, ASTM A501 and ASTM A1085 designated steel. Pipe sections with an ASTM A53 designation also are allowed.
