Cyclic model for concrete in discrete lattice model

In this paper discrete lattice model to simulating concrete subjected to the cyclic loading is presented. Embedded strong discontinuities for propagating the cracks through concrete is used as a basis for developing cyclic loading model. Damage model is used to describe the non-linear response of concrete. Proposed model is suitable for describing reduction of unloading stiffness, which is characteristic of brittle materials, when elastic response is affected by inelastic deformation.
