First-order solutions for the buckling loads of euler-bernoulli weakened columns / Loya, J. A. in Journal of engineering mechanics, Vol. 136 N° 5 (Mai 2010) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 136 N° 5 (Mai 2010) . - pp. 674-679 Titre : First-order solutions for the buckling loads of euler-bernoulli weakened columns Type de document : texte imprimé Auteurs : Loya, J. A., Auteur ; Vadillo, G., Auteur ; Fernández-Sáez, J., Auteur Année de publication : 2010 Article en page(s) : pp. 674-679 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Cracking  Columns  Buckling  Eigenvalues. Résumé : In this work, closed-form expressions for the buckling loads of a weakened column with different boundary conditions are presented. The cracked-column model is based on the well-known method consisting of dividing the column into two segments connected by a rotational linear spring whose flexibility is related to the crack size and the geometry of the cross section. For the formulation of closed-form expressions, the perturbation method is used and the results are compared with those found by directly solving the eigenvalue problem.
