Last-year students in Civ Eng have the chance to familiarise themselves with the modern methods for analysis of reinforced concrete (R/C) structures using the nonlinear finite element analysis method for:
- line element structures (frames)
- planar and 3D structures
In-depth knowledge of the behaviour of R/C members under different stress states (1D, 2D, 3D)
Familiarisation with modern software for the nonlinear analysis of R/C structures (SAP-2000 Nonlinear, ATENA).
Course Content (Syllabus)
Modern methods for analysis of R/C structures.
Range of application of linear methods - Current code requirements.
Nonlinear analysis of R/C frame structures: Model types, Loading protocols, constitutive laws, failure criteria.
Fundamental models for R/C and its constituent materials: Uniaxial compression (of normal and high-strength concrete). Multiaxial compression.
Confined concrete - Reinforcing of complex cross sections.
Moment-curvature and moment-rotation diagrams for R/C members; failure criteria.
Concrete and steel under uniaxial tension.
Bond between concrete and steel.
Point hinge (lumped plasticity) models: Elastoplastic point hinges - Point hinges with any type of constitutive law.
Application of the point hinge method to the analysis of R/C frames.
Nonlinear analysis of planar R/C structures: Constitutive laws for (general) biaxial loading. Nonlinear elasticity models.
Modelling of planar R/C structures - Plasticity models, fracture mechanics models - Applications.
