Instability and strength of monosymmetric i beams / Mohamed Benchiha 

Public ISBD Titre : Instability and strength of monosymmetric i beams Type de document : texte imprimé Auteurs : Mohamed Benchiha, Auteur ; T. M. Roberts, Directeur de thèse ; R. Narayanan, Directeur de thèse Editeur : University College, Cardiff Année de publication : 1986 Importance : 87 f. Présentation : ill. Format : 27 cm. Note générale : Mémoire de Master : Civil and Structural Engineering : Angleterre, University College, Cardiff : 1986 Annexe f. 88 - 90 . Bibliogr. [4] f Langues : Anglais (eng) Mots-clés : Monosymmetric  I-beams Flexural-torsional  instability Pre-buckling  displacement Initial  imperfections Doubly  symmetric  I  beams Index. décimale : Ms00186 Résumé : This thesis is concerned with the problem of flexural-torsional or lateral instability of monosymmetric I-beams. A theoretical and experimental investigation on the subject has been carried out. The energy approach has been used to obtain solutions for the flexural-torsional instability of monosymmetric I beams, including the influence of pre-buckling displacement, and initial imperfections or pre-camber in the plane of major axis bending. Forty-six welded small-scale model beams, including fourteen doubly symmetric I beams, sixteen monosymmetric I beams and sixteen T beams have been tested. All the beams were simply supported and loaded by a central concentrated load applied on the top flange. The test results are compared with existing design curves for laterally unrestrained beams recommended by the European Convention for Constructional Steelwork (ECCS) and the British Standard Specification for the Structural Steelwork in Building. The lower bound design curve recommended by ECCS is in good agreement with the test data presented in this thesis.
