Gestor de consultas para perfiles de acero AISC

Gestor de consultas para selección de perfiles AISC

La AISC (American Institute of Steel Construction) es el Instituto Americano de la Construcción en Acero.

AISCPy establece una base de datos y funciones para consultar el mismo, de manera que con esta se pueda desarrollar aplicaciones de calculo estructural en acero.
