Wind Resistance

Wind load requirements are covered under the national code standards but may vary from jurisdiction depending on wind zones. Wood has inherent characteristics that make it ideal in areas prone to high wind. First, its elastic limit and ultimate strength are higher when loads are applied for a short time, which tends to be the case in high wind events. When structural panels such as plywood or oriented strand board (OSB) are properly attached to lumber framing, they also form some of the most solid and stable roof, floor and wall systems available. When used to form diaphragms and shear walls, they are exceptional at resisting high winds.
