This course supplements the courses Structural Concrete I and II regarding the analysis and dimensioning of reinforced and prestressed concrete structures. It focuses on limit analysis methods for walls, beams, slabs and shells, particularly regarding their applicability to the safety assessment of existing structures and their computer-aided implementation.

Introduction to structural mechanics, statically determinate beams and frame structures, trusses, stresses and deformations, statically indeterminate beams and frame structures (force method)

This course offers the foundation to advanced consideration for structural analysis. This includes the solution of indeterminate systems via use of the Deformation Method and Matric Structural Analysis, as well as the solution of systems with nonlinear material behavior (e.g. due to plasticity).

This course focuses on the axial, shear, bending and torsion load-deformation response of continuous elastic prismatic structural elements such as rods, beams, shear walls, frames, arches, cables and rings, and structures that contain such elements. Additional special topics may be addressed time-permitting.

Contents: Introduction, historical development of structural concrete, materials and material behaviour (cement, concrete, reinforcing steel, prestressing steel), linear members (axial force, flexure and axial force, compression members and columns, shear, bending and shear, torsion and combined actions), strut-and-tie models and simple stress fields, detailing, basic aspects of membrane elements.

Contents:Prestressed concrete (introduction, prestressing systems, load-deformation response, detailing, girders, slabs), plates (introduction, yield criteria, equilibrium solutions, yield-line analysis, shear and punching, serviceability).
