ASCE/SEI 7-05, "Minimum Design Loads for Buildings and Other Structures," represents a significant evolution in wind engineering, introducing the concept of Velocity Pressure exposure coefficients based on ultimate wind speeds and three distinct wind exposure categories (B, C, D). This paper provides a systematic procedure for calculating design wind pressures on Main Wind Force Resisting Systems (MWFRS) and Components & Cladding (C&C) as per ASCE 7-05, including the analytical method, parameters (wind speed, exposure, topographic effects, gust effect factor), and step-by-step calculations for a low-rise building example.
