NEW DELIVERABLE - High-Strength Reinforcement for Concrete: Development Length and Lap Splices
Development and Splice Lengths for High-Strength Reinforcement
fy > 60 ksi
This TWO-VOLUME REPORT and PRESENTATION outlines the results of testing to inform guidance on utilization of high-strength steel reinforcing bars in concrete structures published in current and future editions of ACI 318 Building Code Requirements for Structural Concrete. The use of Grade 80 and Grade 100 reinforcement - considered specifically for gravity, wind, and seismic loading - aids in reducing congestion within members, providing better consolidation, and speeding up construction time. The objective of this research program was to evaluate the development of high-strength reinforcing steel, establish a design expression for the development and splicing of this reinforcing steel and evaluate splices at the base of walls subjected to earthquake demands.
