How to Make Hurricane Resistant metal Building Structures ? |
Posted: October 15, 2019 |
If you live in an area where hurricanes can happen, it makes sense to make your metal steel buildings hurricane resistant. Steel structures are designed to last for decades, and heavy storms with gale-force winds can have a major impact—even if they just roll around once in a while. Hurricanes Are Hard on Steel Buildings Sustained winds of 74+ miles per hour and wind gusts that can exceed 250 mph can do a lot of damage even to a sturdy structure. The windward wall of a steel building may be under more than 65 pounds of pressure per square foot from the air rushing in opposition. On the other three sides, the suction caused by lower air pressure can pull walls outward. Add in the rain, and there’s the potential for foundation damage and corrosion. If a surge of water hits the steel building during flooding, the pressure on the walls is even more intense and can cause a collapse. The swirling winds are also able to lift away roofing materials. Steel Buildings Designing for Hurricane Zones If you live in a city that has a high risk for tropical storms, your steel and metal building design may require to include hurricane resistance from the outset when you get your permit. Homeowners’ Associations may have a similar requirement. How can you design a metal steel building that can withstand the pressure?
What about Retrofitting? Hurricane structures provide a relatively low-cost way to reinforce small steel structures such as sheds, garages, and workshops. It will typically include anchors and metal building straps and plates. The studs, trusses, and rafters are secured using these straps, adding strength to the internal structure. If the steel buildings have windows, these will also need protection such as storm shutters. Larger buildings may require more extensive and customized retrofitting.
