Original Note:

Steel loses its structural strength long before it melts. For the WTC to collapse, the beams did not have to melt, as it was enough that they lost their structural strength due to high temperature. https://www.researchgate.net/figure/Reduction-of-yield-strength-with-temperature-for-different-steel-grades_fig3_281580209
