Fatigue performance of stud connectors in steel-ECC composite structures after salt freeze-thaw cycles: Experimental study and degradation model

Key Points

• Fatigue performance deteriorates after exposure to salt freeze-thaw cycles, indicating a risk for composite structures.
• The experimental study showed that interconnected deterioration led to reduced structural reliability over time.
• Observational analysis of stud connectors revealed a need for further understanding of fatigue under environmental stressors.
• Potential implications underline the importance of exploring better materials or protective methods for durable construction.
