Wind Loading Demystified

Feb 02, 2021 12:00 pm - 1:30 pm

Windspeed and wind pressures are concepts that often causes confusion and anxiety for many building professions when it comes to component and cladding design and specifications. In this course, the speaker will break down the differences between Strength Design and Allowable Stress Design approaches and discuss when each design methodology is appropriate for component and cladding design. Wind load maps for Oregon have changed in the recent iteration of the 2019 OSSC resulting in lower wind pressures in many local areas potentially lowering the cost for components and cladding systems. The speaker will discuss how these lower wind pressures can be applied to specifying windows to be more structurally efficient while maintaining separate water test pressure performance criteria. Roofing and associated components will also be explored.
