3D Modeling of Damage and Cracking in Anisotropic Concrete and its Application in Seismic Analysis of Dams, Ph.D. Dissertation Sharif University of Technology ; Ghaemian, Mohsen (Supervisor)
Abstract
A finite element model for seismic analysis of concrete arch dams is proposed. Material inelasticity as well as joints nonlinearity is considered. In order to provide a precise description of concrete response, a novel plastic-damage constitutive model for plain concrete is developed. For this purpose, the microplane theory is proposed for overcoming the deficiency of available anisotropic continuum plastic-damage models in reproducing the true anisotropic nature of damage in multidimensional loadings.Based on the microplane theory, the degeneration process in concrete is considered along with plastic deformations. Using the principle of strain energy equivalence, a transformation between...
