This data, in HTML table form, shows assumed specifications for each WTC 1 core column at Floor 98 inferred from information available; predicted maximum temperature at 102 minutes for various proportions of FRC removed; demand and capacity; reduction in yield strength at maximum temperature; and demand:capacity ratio (cold and maximum temperature). Printing is better with Mozilla as it will shrink to fit the page width and works in portrait; Explorer needs landscape orientation and page breaks are in the wrong place. There are 13 columns per line. Alternatively, adjust text size for best viewing of data. See review of results and further discussion in Fires Part Four.

Some variables are self-explanatory. Here is a full list, with further details as necessary.

Column number; yield strength (ksi); cross-sectional area (ins^2); the nnn weight per linear foot W14xnnn specification assumed for the column (lb/ft); cold capacity of the selected member size (tons); cold capacity based on the calculated demand and NIST published d/c ratios; width W1 or d as viewed normal to the web and including the short tf sides of the flanges (ins); width W2 or bf as viewed normal to a flange; total heat absorbed after 102 minutes for totally exposed member (MJ); final column temperature with FRC totally stripped off on all four sides based on total absorption but without taking into account flame or gas temperature limits (C); final temp also under fully exposed conditions but imposing an 850C limit; final temp assuming one side or one-quarter of FRC removed; final temp with FRC fully intact; axial gravity load at floor 98 (tons); cold capacity of the selected member repeated as before for comparison with demand; yield strength reduction factor with all FRC removed; strength reduction factor with one side or one-quarter of FRC removed; strength reduction factor with all FRC intact; final column capacity after 102 minutes with all FRC stripped off (tons); final capacity with three-quarters of FRC remaining; final capacity with all FRC remaining; pre-impact cold demand / capacity ratio; final d/c ratio with all FRC removed; final d/c ratio with one-quarter of FRC removed; final d/c ratio with all FRC intact.
