Structural Fire Resistance
    
  Computer simulation based on a NIST fire test conducted during the investigation of the collapse of the World Trade Center towers. Image shows flames impacting a model of a WTC steel floor truss without any fire-resistant insulation. Colors in the simulation show the variation in gas temperatures.
