The 2024 International Building Code (IBC) references ASCE 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures. Component and cladding (C&C) roof wind pressures calculated using ASCE 7-22 were simplified but still require nail spacings for wood structural panels which are significantly reduced from pre-2021 IBC prescribed minimums. Uplift connectors for gable endwall rake overhang outlookers to the endwall require engineering or can be sized based on prescriptive tables to account for C&C loads at roof edges. Uplift connectors at rafter or truss bearings are based on main wind force resisting system loads. The 2024 IBC and other code-referenced standards, updated to ASCE 7-22, have uplift connection load tables that can be used to size roof-to-wall uplift connections.
