One-dimensional models for the spacial behaviour of tapered thin-walled bars wi...
Andrade, Anísio Alberto Martinho deTapered thin-walled bars are extensively used in the fields of civil, mechanical and aeronautical engineering. The competitiveness of tapered structural members is hindered by the fact that their spatial behaviour is still poorly understood and by the lack of rational and efficient methods for their analysis and design. The present thesis aims at providing a contribution to overcome these drawbacks, by (i) deve...
Lateral-torsional buckling of singly symmetric web-tapered thin-walled I-beams:...
Andrade, Anísio; Camotim, Dinar; Dinis, P. BorgesThis paper assesses the global performance and the underlying assumptions of a recently developed one-dimensional model characterising the elastic lateral-torsional buckling behaviour of singly symmetric tapered thin-walled open beams, which is able to account for the influence of the pre-buckling deflections. A comparative study involving the critical load factors and buckling modes yielded by (i) the one-dime...
