Implication

Observational analysis reveals degradation of concrete with increased temperature and holding time, suggesting enhanced fire-resistant design is needed.

Key Points

Stress–strain curve indicates a transition from brittle to ductile behavior in concrete after fire exposure, highlighting crucial changes in structural performance.
As temperature rises, the mass loss rate increases and the number of cracks in the concrete also rises, indicating significant degradation of mechanical properties.
Numerical simulation methods were employed to analyze concrete's response under varying temperatures, establishing a robust constitutive model based on the Weibull distribution.
Findings underscore the importance of considering both temperature and hold time when assessing and repairing concrete affected by fire, supporting fire-resistant design principles.
