Abstract

In the second and final part of this paper, the time-dependent analysis of a monosymmetric composite wood-concrete cross-section is presented. The relaxation procedure is used to assemble the stress and strain vectors due to creep and shrinkage effects. These are solved using the finite difference method and finally an illustrative example is used to demonstrate the method.

Resume

Dans la seconde et dernière partie de cet article, on présente l’analyse en fonction du temps d’une section transversale composite bois-béton monosymétrique. La relation fournit une méthode pour relier les vecteurs des contraintes et des déformations dues aux effets du fluage et du retrait. On donne ensuite une application de la méthode des différences finies, et enfin on illustre la démonstration par un example.
