Sažetak
This work presents a proposal of the new numerical three-dimensional (3D) model for describing the nonlinear behaviour of concrete in reinforced and prestressed concrete structures. Nonlinear behaviour of concrete is described by an elastoplastic material model which is based on the Mohr-Coulomb law for dominant compression stresses and the Rankine law for dominant tensile stress. The nonlinear behaviour of a reinforcement bars and prestressed tendons is modelled by the one-dimensional (1D) elasto-viscoplastic model. The tendon element geometry is described by the second order space function which is determined by its projections. The transfer of prestressing force on the concrete is modelled numerically. The developed models for concrete and reinforcement are implemented in the computer programme for a 3D analysis of the reinforced and prestressed concrete structures where the structures are discretized by 3D finite elements with an embedded 1D element of reinforcing bars and prestressed tendons. The computer program PRECON3D for practical engineering applications in the nonlinear analyses of the 3D reinforced and prestressed concrete structures is developed.
