Computational Modelling of Structures

The course focuses on finite element modelling of civil and building engineering structures, both linear and nonlinear. The choice of element types, constitutive models, selection of material parameters, boundary conditions, loading schemes, control procedures and other modelling aspects are discussed and critically reviewed, from a users point of view. Possibilities, limitations and pitfalls of analysis types and models are treated, in connection to the underlying theory and algorithms. Attention is given to interpretation of results, equilibrium checks, convergence checks and judgment of output in relation to engineering design rules. Students learn to critically approach or even distrust computer output, rather than naively show off exciting colour plots.

The course is based on real-world engineering examples, augmented by small-scale test simulations and academic exercises. Upon an introduction to linear and nonlinear finite element analysis procedure, the course focuses on applications in the fields of steel, reinforced concrete, and masonry structures. Specific topic such as elasto-plastic analysis, geometrically nonlinear options, discrete cracking approach, smeared cracking approach, and interface models are treated together with recent research on reliability analysis and seismic analysis.
