Course content

Calculation and design of slabs, column-supported flat-slabs, foundations and shells. Compression-field theory for panels, plates and shells. Iteration method for strength analysis of concrete shells. Thin-shell theory for axisymmetric cylinder shells. Calculation and capacity of structures deteriorated by reinforcement corrosion and alkali-silica reactions.

Learning outcome

Concrete Structures 3 is the final course the students meet in their specialization within design of concrete structures. Together with Concrete Structures 1 and 2, it offers the students a comprehensive introduction to structural analysis and design of concrete structures. All courses present the theoretical background for the methods of analysis and design as implemented in the design code, Eurocode 2. The main topics of Concrete Structures 3 are walls, slabs, shells and foundations, and assessment of deteriorated structures. Concrete Structures 3 has these learning objectives.

Knowledge: - The theoretical background for: Compression field theory - Strut and tie models - Different methods for design of concrete slabs - Punching shear in concrete slabs - Design of concrete shells - Design of simple foundations - Calculation and capacity control of deteriorated structures. Skills: - Strut and tie modelling according to Eurocode 2 - Design of membranes by using the compression field theory - Calculation and design of two-way slabs according to the theory of elasticity, the yield line method and the strip method. - Design of flat slabs - Capacity of punching shear according to Eurocode 2 - Design of concrete shells with the sandwich model - Capacity of concrete shells with the iteration method - Design simple foundations according to Eurocode 2 - Calculation and capacity control of deteriorated structures. General competence: - The theoretical background for structural analysis and design of concrete structures - Background for requirements in Eurocode 2.

Digital competence: The majority of the taught methods are applied by means of various relatively simple digital tools (software) in the industry. The strategy in the course is therefore to focus on understanding the theoretical background of the methods. Sustainability competence: Methods for determination of CO2-equivalent emission from the construction-process (cradle-to-gate) are introduced in examples and exercises. This gives background for conceptual choices.
