Post-fire mechanical properties and constitutive modeling of low-yield-point LY160 steel subjected to different cooling methods

Key Points

• Post-fire, LY160 steel exhibits variable mechanical properties depending on cooling methods employed.
• The evaluation reveals a 20% decrease in yield strength with rapid cooling protocols among tested samples.
• Assessment using mechanical testing and constitutive modeling reveals insights into performance under thermal stress.
• Understanding these changes supports improved fire safety standards and material selections for structural applications.
