Learning outcomes:

The scientific knowledge needed for the optimum design of the building is a combination of structural elements with the complexity of the physical and the economical factors. This course teaches the integration of different structural materials to achieve a functional product. Furthermore, the technological, organizational and economical factors are continuously present in the design process. The course has the following goals: 1. Basic understanding of material properties, mainly masonry, concrete, reinforced concrete, prestressed concrete, wood and steel. 2. Ability to calculate the structural elements of a simple structure. 3. Ability to decide/select the appropriate structure: reinforced concrete vs masonry or wood vs steel. 4. Understanding of the main standards and regulations that govern the design process. 5. Ability of a correct usage of the main design codes for loading, structural materials, structures.
