The "Isotacas" (wind speed maps) now use a 50-year return period with increased regional velocities based on more recent meteorological records.

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). manual de dise%C3%B1o por viento cfe 2020 pdf capo

The published by the Comisión Federal de Electricidad (CFE) is the definitive technical guide for structural wind engineering in Mexico. This 514-page document provides the rigorous mathematical and empirical frameworks necessary to ensure that infrastructure—from simple warehouses to complex power plants—can withstand aerodynamic forces. Core Objectives of the 2020 Manual

The 2020 update introduced several critical changes compared to the previous 2008 version to account for climate change and better data collection: The "Isotacas" (wind speed maps) now use a

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 ) temporary sheds)

The manual uses a specific formula to determine the wind speed a structure must be designed to resist:

(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
