Course detail

Steel Constructions and FEM

FSI-ZOKAcad. year: 2020/2021

The course combines the areas of steel structure design and computational modelling using a finite element method in a single logical framework. Students obtain basic information from the theory of steel structures in building - limit states theory, dimensioning of steel structures, joining of elements of building structures, design hangars. Students will also deepen their knowledge of finite element method and solution of nonlinear contact problems, use of nonlinear material models, solution of fast processes and modal analysis and Eigen vibration. The practical part is focused on deepening the knowledge of engineering analysis in the Ansys Workbench system with a focus on steel structures and more advanced nonlinear problems.
