FE analysis of the interaction between moisture migration, creep, shrinkage and cracking

conference paper
The interaction between moisture migration, creep, shrinkage and cracking in ce-mentitious ntaterials, snelt as masonry, is studied in this paper. A decoupled approach is followed. As driving force for shrinkage, the pore Immidity is solved for from a diffusion equation. Subsequently, the evolution of the shrinkage strain field is derived and employed in a mechanica' analysis ignoring stress or cracking influence on the pore huntidity. Creep is accounted for by visco-elasticity, while the initiation and growth of cracks are simulated in a smeared way by softening, anisotropic Rankine plasticity. In this manoer different tensile strengths parallel and perpendicular to bed joints in masonry are accounted for.
