Course abstract

Subject discusses the composite slabs, beams and columns according to Eurocode 4. Advantages, planning and erection of composite structures are given. The main equations for verification of bearing capacity taking into account specific reinforcement and amount of shear connectors are shown. Main types of composite columns. Simplified method of design of concrete filled circular hollow section column. MS Excel, AutoCAD, MathCAD programmes are used preparing for further work with BIM software.

Learning outcomes and their assessment

Knowledges about designing of composite slabs, beams and columns according to requirements of EC4; skills to use the technical literature and algorithms for various problem solving; competences to define the task, to choose the method of calculation and evaluate the acquired results. Assessment is carried on the basis of indiviual work presentation and competent conversation about theme.
