Title: Chemo-mechanical finite element model of deterioration of plain concrete structures
Author(s): P. Romanowski, Cz. Cichoń
Appears on pages(s): 85-106
Keywords: finite element,deterioration,chlorides
Abstract:In this paper the degradation of mechanically loaded plain concrete structures under two deterioration mechanism: chlorides diffusion and calcium dissolution, with the influence of the moisture transport in concrete, are considered. It is assumed that the concrete behavior is initially isotropic and described by two scalar damage variables, independently for compression and tension loading conditions. The chemical degradation of concrete is described by means of an additional internal variable, named environmental damage. This damage variable consists with two internal variables which are the measure of deterioration of concrete caused by chloride and calcium ions actions. The usefulness of the proposed method of FE numerical analysis is verified by two examples.
