Design of Steel and Composite Structures

Recommended Prerequisites

Students must have a strong background in mechanical behaviour and strength of materials and structural analysis. Students must already know the basic formulations for the analysis and design of structural steel members and joints according to European rules, including Eurocode 3, Parts 1.1 and 1.8.

Teaching Methods

Classes run under theoretical and practical. In the classes are presented the theoretical concepts and the code formulations for the design of steel and steel-concrete composite structures. Simultaneously, some pratical examples are solved. Students have an active participation throughout the training process, because they have to develop full project works; part of this work is developed in classes and some outside of classes.

The assessment of students is based on the evaluation of the projects developed during the semester and it includes a final presentation and defense.

Learning Outcomes

Transmit the knowledge necessary for the conception, analysis and design of steel structures, steel-concrete composite structures, or consisting of the association of steel with other materials: wood, polymers, glass and masonry, according to European regulations for structural design. In this course unit, emphasis is given to the execution stage, once only a deep knowledge of manufacturing, transportation and erection processes allows to the designer the conception of more efficient structures and therefore more economic structures. Another objective of this course unit is to encourage students to use automatic calculation tools.

The aim is the development of instrumental skills (oral and written communication and problem solving), personal (critical thinking) and systemic (apply in practice the theoretical knowledge and development of self-criticism and self-assessment), essential for the conception, analysis and design of structures.
