Code of Practice for Design Loads (Other than Earthquake) for Buildings and Structures, Part 3: Wind Loads 1987 Edition
The 1987 edition of IS 875 Part 3 outlines the methodology for assessing wind loads on buildings and structures across India, excluding seismic considerations. It details the procedure to compute design wind pressures by taking into account factors such as terrain, topography, building form, and structural components, including gust influences and internal pressure effects. This code is vital for engineers and designers to ensure structural integrity against wind forces using Indian climatic and geographical data.
