Abolladura de estructuras de barras de sección tipo doble-T

A stepped methodology for the evaluation, with limited computational effort critical buckling load factor which produces the instability of the walls of double-T sections is proposed in this work. For this purpose, each wall of the cross-section studied in a local level as a thin plate. It is ratified that it is enough to check the most compressed flange and the web of the most loaded beams of the structure.
