✦ Synopsis

Computer-aided procedures have been developed to allow architects and engineers with no previous computer knowledge to prediet the theoretical fire ratings of different layers of fireproofing materials. The device which permits such a theoretical evaluation is a computer model known as FIRE (Fire Intensity-Resistance Evaluation). Using this procedure a engineer can choose up to three different layers of material to be evaluated under various fire intensities. The layers which can contain water or different transformation products can be considered to be in intimate contact or separated by an air gap. The various layers can be considered to be attached to a heat sink which represents the mass of various structural members of different sizes.

A direetory offifty materials is available for evaluation under.fire exposures of different intensities and durations. Correlations are now being carried out with existing fire tests to insure the best fit for the different temperaturedependent material parameters that are required.
