Este manual es una referencia obligatoria no solo para proyectos de la CFE, sino para la práctica de la ingeniería civil en todo el país y diversos países de habla hispana.
4. Diferencias entre la Versión 2020 y Versiones Anteriores (1993 / 2008)
Contar con el documento es una necesidad legal y técnica para directores responsables de obra (DRO), ingenieros calculistas y arquitectos en territorio mexicano. El cumplimiento estricto de esta normativa previene fallas locales (desprendimiento de láminas, techumbres o muros cortina) y colapsos globales, salvaguardando la inversión económica y la vida de los usuarios. ✅ Conclusión

Tratamiento Avanzado de Presión Interna ( Cpicap C sub p i end-sub 50 años para el Grupo B, 200 años para el Grupo A)
de la Comisión Federal de Electricidad (CFE) representa la actualización más reciente y avanzada para la ingeniería estructural en México. Publicado en julio de 2020, este documento (Capítulo C.1.4) sustituye a la versión de 2008, integrando décadas de experiencia técnica y nuevos datos meteorológicos para garantizar la seguridad de las infraestructuras ante fenómenos climáticos extremos. Aspectos Clave de la Versión 2020
No espere a que un reglamento local se lo exija: actualice sus herramientas de diseño con el CFE Viento 2020.
Define la clasificación de las estructuras según su respuesta al viento:
Puja/Yagya - A Ritual of one or more gods and goddesses in prescribed method by Veda's.
Sankalp – As every sound exists in this universe, this sound also moves in the universe and influences the person for whom the Yagya is being performed. We call it Sankalp. In Sankalp we individualize the effect of Yagya and Mantra. In this Sankalp, The Pandit speaks the person’s name, gotra and all particulars including birth details to make him unique. In other words, Sankalp is like an address to be written on a letter.
Japa – Recite of some particular mantras belonging to some planets or some scripture to appease a planet or god to deliver results. Japa can be from 108 to 125,000+10% or even more which may take even months.
Aarti – A ritual done by Deepak moving around God, taking his obstructions away (in fact, we pray God also as friend, father, child & Guru). In all these emotions, we take care of his problems too. Normally we sing his prayer while doing aarti. Om jay shiva om kara OR “Om Jay Jagadish Hare” is a popular prayer.
Hawan –A method to sacrifice some particular materials in holy fire chanting a specific mantra to appease a planet or god to deliver results. Also called fire-sacrifice, homam, hawan, ahuti etc.
Stotra Path/ Prayers –Recite of some particular Vedic Rhyme belonging to some planet or some scripture to appease a planet or god to deliver results.
Donation - Money or any stuff donated to qualified Brahmin Pandits to acquire his blessings for achievements.
Brahman Bhoj - Letting eat the Enlightened Pandits to get their blessings.
The performance of a planetary yagya creates positive influence from a specific planet. (Sun, Moon, Mars, Mercury, Jupiter, Saturn, Rahu, Ketu). Planetary Yagyas neutralize negative and strengthen positive influence from the lords of the dashas or transits. Dashas are certain time periods in a person’s life, which are ruled by certain planets. Great support of nature can be reached.

Royal Yagyas use longer, more complex mantras than the special intention yagyas. This yagya is for wealth and prosperity. It is a yagya done for people who are currently earning money. It is not a way to get out of debt. If you already have one or more solid streams of income, this yagya tends to enhance the income.
