Steel Constructions and FEM
FSI-ZOKAcad. year: 2019/2020
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.
Learning outcomes of the course unit
Students will acquire knowledge of the theory of limit states, design of elements with tension and compression loading and learn how to practically use computational methods of structural mechanics, design of construction structures. Students will realize the difference between the design of engineering and civil-engineering structures. Students become familiar with the creation of complicated computational problems using the finite element method focused on nonlinear contacts, bilinear material models, solution of fast processes and modal analysis.
Knowledge in area of solid mechanics, strength of materials, material science.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Course-unit credit is awarded on the following conditions: active participation in the seminars, elaboration of the project from laboratory and computational exercises.
Examination: course is finished by the final test. In the test, the student has to prove knowledge from lectures and laboratory exercises.
Language of instruction
Familiarize students with design of steel constructions. Demonstrate assembly processes, dimensioning and design principles. Extend students' knowledge about complicated computational tasks using finite element method, including its application in Ansys Workbench.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is recommended; attendance at laboratory practicals is obligatory and checked by the lecturer. Compensation of missed lessons depends on the instructions of course supervisor.
