Acceptable Elongations and Low-Cycle Fatigue Performance for High-Strength Reinforcing Bars

Acceptable Elongations and Low-Cycle Fatigue Performance for High-Strength Reinforcing Bars

This project will define acceptable uniform elongations and low-cycle fatigue performance for high-strength reinforcing bars (HSRB) in concrete construction based on bar properties and seismic hazard level. HSRB are defined as bars having a yield strength of 80 ksi or higher. This project will identify key parameters affecting the fatigue performance of HSRB and deliver specification limits that will ensure minimum performance is achieved in production of HSRB.
