Wind loading analysis is an essential part of the building process. J.P. Schilke, Civil & Agricultural Engineering, If when selecting the MWFRS or C&C methods you are unable to select FBC and the circle to the right is RED, that means that you dont meet all of the criteria to select the FBC Alternative method. In areas with heavy snowfall, the snow load on a structure can be quite significant and must be taken into account during the design process. After hitting the return key, you should get the following output: The same can be performed by other countries or locations including Australia, UK, Canada, and European nations such as Germany, Italy, France, etc. endobj Since a ZIP code (or postal code) is not an exact site location, the wind speed map needs extra information to recognize this is a zip code. & An enclosed building is a building that does not comply with the requirements. by the building official. 6-15), qh = 0.00256*Kh*Kzt*Kd*V^2*I (qz evaluated at z = h).
