The Indian Standard IS : 875 (part 3) –1987 Code of practice for Design Wind Load has presented a wind zoning of India based on an average peak gust velocity of 3 seconds with a 50 year return period. Local building codes and building departments can also require engineered plans specific to their topography and conditions that exceed the recommendations of the IRC and WFCM, it is always a good idea to verify your plans with a local building official prior to construction. Current WInds. Every manufactured home must be designed according to the federal Manufactured Home Construction and Safety Standards at 24 CFR 3280, known as the HUD Code. The manufactured home producer designs the home to resist the wind load, which is measured in pounds per square foot. But the process of taking those values and creating design wind load values is dependent on a lot of other factors that are site and design specific, and those are clarified in the structural commentaries. The home must be capable of transferring these imposed lateral loads to the home’s stabilizing devices without exceeding the allowable stresses and other deflection requirements. Wind Zone I, Wind Zone II and Wind Zone III are identified on the basic wind zone map above. Homes designed and constructed to a higher Wind Zone can be installed in a lower Wind Zone (a Wind Zone III home can be installed in a Wind Zone I or II location).
