The is a cornerstone of Mexican engineering. First published in 1969 by the Comisión Federal de Electricidad (CFE), it has become an indispensable reference in Mexico and across Latin America, reflecting the technological expertise gained from designing, building, and operating major infrastructure. The wind design chapter (C.1.4) is part of the "Structures" section and is essential for any civil engineer in Mexico.
3. Procedimiento General para Calcular la Presión de Diseño
However, there is an important clarification to make before proceeding: for general civil works. The primary wind design standard in Mexico for buildings and civil structures is the “Manual de Diseño de Obras Civiles – Diseño por Viento” (MDOC – Viento) , which was most recently updated as part of the MDOC 2015 (with some updates adopted into the NTCD 2020 / NTC-DF 2020 for Mexico City).
El PDF oficial del manual de diseño por viento CFE 2020 (de obras civiles diseño) se divide en 12 capítulos y 7 apéndices. Los más relevantes para el diseño práctico son: The is a cornerstone of Mexican engineering
Es fundamental para el diseño seguro de edificaciones, torres de transmisión, estructuras industriales, chimeneas, y estructuras singulares.
La versión 2020 introdujo ajustes técnicos críticos que los ingenieros deben notar:

CFE MDOC defines 4 terrain types, unchanged in 2020:
: There are significant modifications to the mean annual minimum daily temperatures (located in Appendix 4C), which directly influence air density and resulting wind pressures. Probabilistic Approach
La actualización de 2020 introdujo cambios significativos respecto a la edición de 2008: he performed a dynamic analysis
La velocidad regional debe ser modificada por las condiciones locales de la zona de desplante (rugosidad del terreno y topografía) mediante la siguiente expresión:
: Mateo had to classify the tower by its response to the wind. Because of its height and flexibility, he performed a dynamic analysis
