Fire Design of Gypsum Wall Board over Mass Timber

Technical guidance on fire-resistance ratings of mass timber members achieved by combination of direct-applied gypsum wallboard and inherent timber char. Covers code paths and design options for demonstrating FRR when mass timber is covered with gypsum wallboard, tested assembly methods, calculation design methods including Component Additive Method (CAM) from IBC 722.6 and IBC 722.7, and AWC's Fire Design Specification methodology. Includes practical examples across different construction types and applications, with references to companion fire design resources.
