High-cycle fatigue performance of Grade 600 steel reinforcing bars (Sep. 2025)

Durability is critical for infrastructure exposed to repeated loading.

This paper investigates the fatigue performance of 600 MPa reinforcing steel under high-cycle loading conditions, typical in bridges, wind farms and other critical infrastructure. It provides early-stage data on how high strength steel performs over time under repeated stress.

The findings support the safe use of SENSE 600® in fatigue-sensitive applications, enabling material efficiency and lower embodied carbon without compromising long-term performance.
