Performance-based design of structural fire resistance entails three steps. This standard provides methods for the first of these steps.

  1. Determination of the fire exposure to the structure.
  2. Calculation of the thermal response of the structure to the fire exposure.
  3. Production of the structural response. 

This standard addresses fully developed fire exposures, including fully-developed fires within an enclosure and localized fires that are not affected by an enclosure. Fires within an enclosure are considered to be spatially uniform, while local fire exposures are not.

Topics covered in this standard include:

  • Determining whether a fire exposure should be considered a local fire or an enclosure fire.
  • Predicting fire exposures within an enclosure.
  • Predicting heat fluxes from local fires.
  • Documentation of the analysis
  • Extensive commentary providing background and guidance for the requirements in the standard.
