High Strength Steel Reinforcement for Bridges

The first objective of this research is to generate datasets of key mechanical properties (tensile yield, compressive yield, ultimate stress and strain, and total elongation) for ASTM A706 Grade 80 reinforcing steel, to determine how these properties differ from Grade 60 reinforcement, and if appropriate, modify design equations based on the datasets so that the high strength reinforcement can be used for structures in seismic regions. The second objective is to characterize the failure mechanisms and measure the shear capacity of connections containing Grade 80 steel reinforcement. It is anticipated that the shear testing will result in modified shear capacity equations for systems containing Grade 80 steel reinforcement.
