Course abstract

Some specific aspects in design of concrete, steel and timber structurs, as well as in foundation design are examined in this course.
Concrete part include topics on 2-nd order analysis of concrete columns, Strut-and-Tie modelling for hard loaded concrete structures, progressive collapse of reinforced concrete buildings.
Design of thin walled steel structural elements as well embedded steel retaining walls and coposite steel and concrete elements are mastered. Actual topic devoted to choice of steel for building taking into account the risks of brittle collapsing.
Topics devoted to timber structures cover design problems of cross laminated timber, 2nd-order analysis of hard loaded glue laminated timber columns, behaviour of bracing system etc.
Topics in part of foundations cover problems arising when neighbouring foundations are designed and built up, and measures for avoiding of unfavourable effects are taken under discussion.

Learning outcomes and their assessment

Knowledge: about behaviour of structures, their elements and fasteners in joints under complicated loading conditions, on advanced solutions of structures, about mutual impacts of neighbouring buildings and/or technological equipment. Test- conversation
Skills: to examine stress- strain development in hard loaded sections of elements and fasteners, to assess (by calculation) mutual impact of neighbouring foundations. Independent work
Competence: Ability for critical assessment of behaviour of structures and elements, as well as impacts of neighbouring foundations. Defence of independent work, test.

Requirements for awarding credit points

Credit test (assessed by mark) is passed if:
• 80% of lectures are attended
• The independent work has been successfully developed and the results of the conversation are positive.
• The student is able to discuss on course content .
Mark is awarded correspondingly to quality of independent work and competence demonstrated during conversation on topic.
If the attendance of lecutres is less than 80%, an aditional independent work is asigned.

Description of the organization and tasks of students’ independent work

The task for content and structure of independent work is given to student basing on his/her choice between concrete, steel, timber, foundations topics.

Criteria for Evaluating Learning Outcomes

Quality of independent work and results of discussion on topic.
