Recent Developments

The novel GBT applications and formulations addressed in this paper concern (i) the development of distortional buckling formulae (using the conventional GBT), (ii) the buckling analysis of mem­bers (ii1) with arbitrary cross-section shapes (branched and/or closed multi-cell) and (ii2) made of isotropic/orthotropic elastic or isotropic elastic-plastic materials, (iii) the vibration analysis of isotropic/orthotropic elastic folded-plate members (loaded or unloaded) and (iv) the post-buckling analysis of isotropic/orthotropic elastic folded-plate members. This sequence is kept in the presenta­tion and the various applications and/or formulations are grouped according to the type of structural analysis (buckling, vibration or post-buckling).
