Buildings are also classified by their response to wind (Types 1 to 4), ranging from rigid structures to those highly sensitive to dynamic effects. Calculating Design Wind Speed ( VDcap V sub cap D )
(Regional Velocity): The maximum probable wind speed for a specific zone, typically measured as a 3-second gust at 10 meters height. FTcap F sub cap T manual de dise%C3%B1o por viento cfe 2020 pdf capo
The manual uses a specific formula to determine the wind speed a structure must be designed to resist: Buildings are also classified by their response to
(Exposure/Size Factor): Accounts for terrain roughness (e.g., urban vs. open sea) and the height of the structure. Sistema Viento | Gerencia de Ingeniería Civil open sea) and the height of the structure
The primary goal of the CFE 2020 manual is to establish uniform criteria for calculating wind loads on structures across Mexico, a country with diverse wind climates including hurricane-prone coasts and high-altitude plateaus. Unlike many local building codes that are city-specific, the CFE manual offers a national standard often adopted by municipalities that lack their own specialized regulations.
(Topographic Factor): Adjusts for local terrain features like hills or cliffs. FAcap F sub cap A
Structures are categorized into four groups ( A+, A, B, C ) based on their importance and the risk associated with their failure (e.g., nuclear plants vs. temporary sheds).
