Résumé

Dans l’analyse des structures soumises à des efforts statiques ou dynamiques, il est souvent très important de comprendre le comportement des systèmes indéterminés. Dans des articles antérieurs [1, 2], les auteurs avaient essayéde développer une méthode pour l’étude de simples éléments de structure soumis à des efforts cycliques consistant en déplacements alternés d’égale amplitude qui déterminent des déformations plastiques. On étudie ici théoriquement des systèmes de poutres à deux et trois articulations dans des conditions semblables d’ambiance et qu’on compare avec d’autres résultats d’expériences (Royles [3]). Pour prédire le comportement des systèmes indéterminés, on se sert de modèles présentant un moment de flexion cyclique, et mis au point d’après des essais en flexion pure. A des fins de comparaison avec le comportement sous sollicitation cyclique, on a aussi effectué l’étude statique de ces systèmes.

Summary

In the analysis of structures under static or dynamic loading on understanding of the behaviour of indeterminate systems is often most important. The authors, in their previous papers [1, 2], have attempted to develop a method for the study of simple structural components under cyclic loading consisting of controlled alternating displacements of equal amplitude producing plasticity. In this paper two and three hinge beam systems are analysed theoretically under similar ambient conditions and compared with experiments (after Royles [3]). Cyclic moment-curvature models, developed from pure bending tests, are applied to predict the behaviour of indeterminate systems. Static analyses of these systems are also carried out to compare the responses with cyclic behaviour.
