Summary
Beam temperature at each failure event in NIST's finite element model of the north-east floor framing of WTC 7, compared with the ASTM E119 average steel temperatures of 538 °C (columns) and 593 °C (floor beams). Based on McAllister et al. (2008), p. 353, and National Institute of Standards and Technology (2008), p. 21.
