Límites de esbeltez para soportes de hormigón con sección rectangular

Límites de esbeltez para soportes de hormigón con sección rectangular

Abstract

Cuando se proyecta una columna de hormigón armado, la mayoría de normativas especifican que los efectos de segundo orden deben ser tenidos en cuenta a partir de una esbeltez mínima, normalmente asociada a una cierta pérdida de capacidad de carga respecto a una columna no esbelta. En este trabajo se proponen expresiones analíticas para estos límites, deducidas a partir de los principios de la mecánica estructural. Los resultados obtenidos con etas expresiones se han comparado con los procedentes de un análisis de segundo orden mediante un modelo de análisis no lineal, obteniendo una correlación muy buena
