This course supplements the courses Structural Concrete I and II regarding the analysis and dimensioning of reinforced and prestressed concrete structures. It focuses on lower bound and upper bound limit analysis methods for girders, discs and shells, particularly regarding their applicability to the safety assessment of existing structures.
Enhancement of the understanding of the load-deformation reponse of reinforced and prestressed concrete; refined knowledge of models and ability to apply them to general problems, particularly regarding the structural safety assessment of existing structures; awareness of the limits of applicability of limit analysis methods and ability to check their applicability.
Fundamentals (structural analysis, theorems of limit analysis, applicability of limit analysis methods); shear walls and girders (stress fields and truss models, failure mechanisms, deformation capacity, membrane elements with yield conditions and load-deformation behaviour); slabs (equilibrium solutions, yield conditions, failure mechanisms, shear in slabs); prestressed concrete for plate and shell structures; long term effects; complements.
