ACI ITG-8R-10

This guide provides recommendations on design provisions for the use of ASTM A1035/ASTM1035M Grade 100 (690) deformed steel bars for reinforced concrete members. The recommendations address only those requirements of ACI 318-08 that limit efficient use of such steel bars. Other code requirements are not affected.

This guide includes a discussion of the material characteristics of Grade 100 (690) ASTM 1035/A1035M deformed steel bars and recommends design criteria for beams, columns, slab systems, walls, and footings for Seismic Design Category (SDC) A, B, or C, and also for structural components not designated as part of the seismic-force-resisting system for SDC D, E, or F.
