Figure 1: The Component Additive Method (CAM) approach sums the fire-resistance times for each component to determine the total fire-resistance rating of the assembly. The table was created by AKF Group based on information from the 2018 edition of the International Building Code (IBC) 722.6, “Wood assemblies,” and “Analytical Methods for Determining Fire Resistance of Timber Members” by Robert H. White.
