Original Note:
Steel does not need to melt for a structural failure to occur. The strength of steel remains essentially unchanged until about 600°F. The steel retains about 50% of its strength at 1100°F. https://www.aisc.org/steel-solutions-center/engineering-faqs/11.2.-steel-exposed-to-fire/#9370 Typical temperatures in a jet-fuel fire can range between 1000°F to 1500°F. https://apps.dtic.mil/sti/pdfs/AD0415380.pdf
