PGSuper - Diseño de vigas de hormigón pretensadas y postensadas (AASHTO LRFD)

[Rapaig]

Estimados,

PGSuper, es un software, al parecer bastante potente, fiel a la norma LRFD, y por el momento, de código libre. Es muy usado en el estado de Washington, y es ahí justamente dónde lo conocí, además de tener bastantes programitas que pueden usar con puentes. Link: http://www.wsdot.wa.gov/eesc/bridge/software/

Si bien, hace tiempo di con este software, no lo seguí por dos razones:

   
• No tenía diseño con AASHTO STD, (uso más común en Chile)
• Y simplemente no es muy conocido

Ahora que lo encontré y está entrando más fuerte el diseño por AASHTO LRFD, vale la pena mirar que entrega el Software.

Saludos!

PD: No olviden de que los software son solo un apoyo, no descansen en sus resultados, hagan sus planillas y/o cálculos a mano para verificar que el procedimiento es correcto.
