In conclusion, it doesnt appear based upon the examples we have checked that there is any clear advantage to using FBC 17 rather than ASCE 7. Contact BuildingsGuide for quotes on safe and durable prefabricated steel buildings. have The first step of the software is to pull the wind speed or ground snow load out of the design code based on the user input location or zip code. To answer this we did a comparison of a simple gabled building using FBC 17 vs ASCE 7-10. This is particularly important for tall structures, such as skyscrapers, which are more susceptible to wind loads due to their height. An additional reference is: 09/23/2021 The appropriate wind zone used in design is dependent on where the home will be initially installed. 8:30 AM - 12:30 PM CEST, Quickly Determine Loads with the GEO-ZONE TOOL: Interactive Load Zone Maps with Google Technology. New The wind pressure calculations will show the wind pressure, and area where the pressures are to be applied. And For an enclosed or partially enclosed building to be classified as a Low-Rise building, the following 2 conditions must both be met: For Transverse Load Case the roof pressure coefficient, GCpf, when negative in Zone 2 or 2E, shall be applied in Zone 2/2E for a distance from the edge of the roof equal to 0.5 times the horizontal dimension of the building parallel to the direction of the MWFRS being designed or 2.5*he at the windward wall, whichever is less; the remainder of Zone 2/2E extending to the ridge line shall use the pressure coefficient GCpf for Zone 3/3E.
