Objectives

After the completion of the course the students are able to calculate beam models and composite structures by using finite element method. They learn how to create practice-oriented and computer-aided the various design stages by means of physical, reality-oriented modeling approaches and they are enabled to judge the results for correctness. The thematic focus is especially on issues specific to the steel constructions. Here, in particular, the various possible modeling and calculation variants for steel construction are prepared in terms of the stiffness of the system and the design concepts of the components. The students are guided by the lecturers while working with the programs by their own. The project works to be done individually lead to a very intense addressing of selected aspects of the course contents. The students get in touch very directly with the peculiarities of the application of FEM in steel and composite construction on the basis of practice-relevant examples.

Description

Introduction to beam models in 2D / 3D (spring, coupling, modelling); Examples of load case combinations in accordance with normative rules of steel construction; Cross-section assessment (elastic, plastic, interaction), also taking into account non-linear characteristics of metallic materials; Application of yield theory of joints with calculation of steel construction-specific structures; modelling with combination of global models and local models; Analysis of local effects (component method), local plasticizing and effects on the global system; Computer-aided analysis of typical problems of stability in steel constructions (bending, lateral torsional buckling, imperfection of structure and bearing elements); Modeling of composite cross section and analysis of time-dependent effects (creep, shrinkage); Modelling of steel bridges and steel composite girders.

Prerequisites

Knowledge of the elastic bending theory (determination of internal forces of bar-shaped components and plates). Basic knowledge of metal constructions. Basic knowledge of the finite elements method.

Teaching and learning methods

PowerPoint presentations; Literature; Tablet PC; Digital overhead projector; Board; guided computer training with PC’s.

Examination

Test performance: project work in the form of three project reports including simulation models. The overall score is granted according to the rating "passed" and "failed" for each of the project works. In the project works specific issues are to be analyzed, documented and verified by using FE-methods and software, The project work has the purpose of a more intensive stand-alone dealing with a particular aspect of the teached Contents.
