Code of Practice for Design Loads (Other than Earthquake) for Buildings and Structures - Part 3: Wind Loads (IS 875: Part 3) + Amendment 2016 2015 Edition
The 2015 edition of IS 875 Part 3 outlines guidelines for assessing wind loads on buildings and structures within India, excluding seismic influences. It details procedures for determining design wind velocities, pressure and force coefficients for diverse building configurations and terrain types, while incorporating considerations for wind-induced dynamic phenomena such as vortex shedding and flutter. This code is vital for engineers and designers to secure structural safety against wind forces, especially in cyclone-affected areas.
