Wood Roof Detailing for Wind Uplift

by John "Buddy" Showalter, P.E., M.ASCE

January 17, 2024; 11:00 AM - 1:00 PM Pacific Time

ICC Preferred Provider Course Number: 32696

Seminar Description

Component and cladding (C&C) wind pressures calculated using ASCE 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, increased over ASCE 7-10 C&C wind loads. Between the increase of C&C roof areas assigned to corner and edge regions and the increase in C&C roof pressures, nail spacings for wood structural panels (WSP) are significantly reduced in some cases. Uplift connectors for gable endwall rake overhang outlookers to the endwall require engineering or can be sized based on prescriptive tables to account for increased C&C loads at roof edges. Uplift connectors at rafter or truss bearings are based on main wind force resisting system (MWFRS) loads. MWFRS loads did not change in ASCE 7-16. The International Building Code® (IBC) and other referenced standards have uplift connection load tables that can be used to size roof-to-wall uplift connections.
