Abstract

AbstractThe Effective Modulus Method (EMM), which simulates the effects of local and distortional post‐buckling to establish simplified design methodologies concept, is applied to the determination of the beam strength. This methodology was presented before [1], where the authors tested the results in columns, in comparison with experimental tests. In this approach, local and distortional post‐buckling effects are simulated by changing the mechanical characteristics (namely the elasticity modulus) of the cross‐section of the members. Specifically, the paper presents (i) the proposal of a new design methodology for beams affected by local and distortional buckling modes interaction and (ii) the comparison with experimental tests available in the literature.
