Behaviour and Strength of Thin-Walled Laminated FRP Structures : 9783639703528 : 28 Apr 2015 : One presents several original Generalised Beam Theory (GBT) formulations suitable to describe the behaviour and strength of thin-walled prismatic structural elements (i) of arbitrary cross-sections constituted by elastic isotropic or orthotropic (composite) laminated FRP materials and (ii) subjected to general loading cases and support conditions. Arbitrary cross-sections are handled using a new GBT cross-section deformation description that (i) takes into account global, local, shear and transverse extension deformation and (ii) identifies a new set of deformation modes in cross-sections with closed cells, i.e., the cell shear flow modes, including the torsion mode. The effects of the (i) location of the load application point, with respect to the cross-section shear centre and (ii) transverse normal stresses due to concentrated transversal loads are included in the GBT buckling and post-buc
