Original Note:
It is not necessary for the steel beams to actually melt. Common steel loses most of it's strenght at far lower temperatures (ca. 600°C - 800°C) leading to collapse of the structure. https://www.researchgate.net/figure/Reduction-of-yield-strength-with-temperature-for-different-steel-grades_fig3_281580209
