The purpose of the course is to transfer to the students the tools and operating procedures to deal with the structural design of civil works, also with regard to resistance against seismic actions.
Knowledge and understanding:
- Knowledge about the modeling and analysis of the structural behavior of concrete elements prestressed and steel strucures.
- Knowledge of the structural behavior of special structural elements such as stairs, corner overhang, holes in a slab.
- Knowledge of criteria detailed design and verification of structures in seismic areas.
Applying knowledge and understanding:
- Ability to integrate knowledge in the design of earthquake-resistant structures.
- Ability to use software.
- Apply methods and criteria for the design of a reinforced concrete framed building located in a seismic zone.
- Present and compare different models and tools for assessing the dynamic response of structural systems.
- Identify and define indicators and descriptors to evaluate data and results
- Ability to identify possible and potential connections between the various aspects of a subject and / or of a problem.
- Work together in a working group, defining objectives, activities, tools
- Present and articulate in writing and orally an elaborate group.
- Reflect on the knowledge and skills of their education
- Identifying possibilities for further development of knowledge, skills and competencies.

The exam consists of an oral exam and includes the discussion of the project of the year done by the students in group as part of the course and discussion of the theoretical and computational issues presented during the course.
The students have to complete the following exercises: 1) Design of a prestressed RC element, 2) design of a simple steel joint.
The student must demonstrate complete mastery of the tools used to carry out such design and be able to justify the solutions adopted. It must also demonstrate that you understand the formal, theoretical and practical aspect presented.
The course of Structural Design is made of 9 CFU: 6CFU are assigned to prof. Caterino, the other 3CFU to prof. Ceroni. The final exam is unique with single commission.
