Abstract

In order to establish orthotropic dynamic damage constitutive model for concrete, dynamic increase factors (DIF) were first used for considering strain effects, then based on Sidoroff’s energy equivalent theory, the dynamic damage elastic matrix of elements was found., and Mazars’ damage model was used for calculating damage scalars of principle axial directions, and orthotropic Hoffman failure criteria was adopted, which intensities was modified for damage and DIF. The model was proved by a destroying experiment of a structure under blasting vibration.
