Implication

Investigation revealed significant loss of tensile strength and changes in mechanical properties of GFRP rebars after exposure to high temperatures, highlighting safety implications.

Key Points

Tensile strength of glass fiber-reinforced polymer rebars decreased by up to 37% at 350 °C, indicating thermal vulnerability.
Maximum changes in elastic modulus were limited to 8.3% loss, suggesting some structural resilience.
Analysis involved mechanical testing and scanning electron microscopy to assess temperature effects on material integrity.
Findings stress the importance of evaluating mechanical properties for structural safety in post-fire conditions.
