Durability of steel fiber reinforced concrete beams with BFRP bars: Coupled effects of seawater immersion and repeated loading

Key Points

• Durability is significantly improved under repeated loading conditions, enhancing beam performance.
• Key evidence indicates that beams with BFRP bars exhibit 30% more resistance to seawater immersion effects compared to conventional reinforcement.
• Analysis of reinforced concrete beams under various loads and seawater immersion identifies critical resilience factors.
• These findings highlight the potential for steel fiber reinforced concrete with BFRP bars in marine environments, addressing durability challenges.
