Wind directionality factor (Kd): Calculate the wind directionality factor, which accounts for the fact that wind loads from different directions may not act simultaneously. The exposure category influences the wind pressure distribution on the structure. This wind speed represents a 3-second gust speed at a height of 33 feet (10 meters) above ground level with a 50-year mean recurrence interval.Įxposure category: Determine the exposure category (B, C, or D) based on the terrain and surface roughness at the building site. Wind speed determination: Obtain the basic wind speed (V) for the building location using the maps provided in the code. Here is a summary of the wind analysis process based on the ASCE 7-10 code: The wind load provisions in ASCE 7-10 are used to estimate the wind forces acting on a structure and its components, such as walls, roofs, cladding, and other elements. It provides guidelines and requirements for determining various design loads, including wind loads, that must be considered in the design of buildings and structures to ensure their safety and stability. ASCE 7-10, 'Minimum Design Loads for Buildings and Other Structures,' is a standard developed by the American Society of Civil Engineers (ASCE).
