# 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.
Propiedades de los perfiles y unidades:
