Conceptual design of buildings

Recommended Prerequisites

Students must have a strong background in structural mechanics and strength of materials. They should also have a good knowledge about structural analysis.

Teaching Methods

Classes run under theoretical and practical. In the classes are presented the theoretical concepts and the code formulations for the design of current portal frame buildings or multi-storey buildings. Simultaneously, some illustrative examples are solved. Students participate actively in the process of formation, being asked to present solutions to the proposed problems. Occasionally students are invited to attend lectures by visiting specialists. Tutorial lessons (22.5 hours) will be to answer questions.

Learning Outcomes

Address the key issues involved in the conception of steel buildings. Transmit the knowledge necessary for the analysis and design of steel structures of buildings, according to European regulations for structural design, including Eurocode 3. Deepen the knowledge of the stability of structures and their elements, in particular when applied to steel frame structures.
