Course abstract

Design of single-storey steel frame of industrial building is mastered taking into account moving load and dynamical effects. Specific of large span and multi-storey buildings, tool structures as well as thin shell structures is discussed undertaking actual working conditions, design problems and economics of structures. MS Excel, AutoCAD, MathCAD programmes are used preparing for further work with BIM software.

Learning outcomes and their assessment

Knowledges about design of steel industrial buildings; skills to perform calculation and construction of steel frames and other complicated steel structures according to Eurocodes 1 and 3; competences to define design problem of steel structure, performe design and evaluate the acquired results. Assessment is given on the basis of attendance of lectures results of tests and passed examination.

Requirements for awarding credit points

Passed a test on the first part of course - BūvZ4105 Steel structures I;
Course project BūvZ4106 Steel structures III is succesfully presented and oral examination passed with numerical solution of the task.

Description of the organization and tasks of students’ independent work

Topics for independent work:
- determination of loads on single-storey building,
- calculation of stability and internal forces in the frames,
- design of eccentrically loaded columns,
- design of long-span lattice girder, calculation of cross sections of truss elements,
- preparing to control test – to give short answers from lecture themes

Criteria for Evaluating Learning Outcomes

1-st independent task is accepted, if static calculation of the frame of structure is given,
2-nd independent task is accepted, if design of eccentrically loaded column is presented, 3-rd independent task is accepted, if design of long-span lattice girder is completed. Control test is passed, if at least 75% correct answers are given. Exam is successful, if comprehensive knowledge is presented and typical numerical task solved.
