Concrete elements have used reinforcement to improve concrete behavior. Advances in steel reinforcement have changed the traditional design and application of reinforced concrete elements. This course will describe changes to the ACI 318 Building Code in determining yield strengths of higher strength grades of steel and study effects of higher strength grades of steel (Grades 80 and 100) to support applied member loads. The course will discuss future plans of the ACI 318 Building Code to implement ASTM A1035/A1035M for use in member-reinforced concrete design and recent research that supports proposed advancement in use of Grade 80 and 100 deformed steel reinforcements.

The contents of this course include two recorded presentations from the ACI 2016 Spring Convention:
• Design Efficiencies Using ASTM A1035 Grade 100 in Reinforced Concrete Structure Applications by Salem S. Faza, MMFX Technologies
• Recent Developments with Respect to High-Strength Steel Reinforcement by David A. Fanella, Concrete Reinforcing Steel Institute

1. Describe the advances steel reinforcement is making to create new higher strength materials and describe possible advantages in design and cost of replacing normal Grade 60 steel with higher Grade steel in member design.
2. Identify the steel reinforcement grades currently permitted today for flexural, axial, shear, torsion, temperature and shrinkage reinforcement applications, and explain the effect of higher grades of steel on concrete beam and column designs for seismic and non-seismic design applications.
3. Describe the 0.2 percent offset method that is now part of the ACI 318-14 code and how this test method changes the measured yield strengths of 80 Grade and 100 Grade steel.
4. Describe how higher strength reinforcement products can improve concrete designs and concrete construction by reducing reinforcement bar congestion.
