Training objectives
- The course provides advanced knowledge of civil structures seismic design, with particular reference to the retrofit of existing buildings, taking into account the economic sustainability of different intervention techniques. The design approach is developed within the current national legislation, and within the wider framework of the Eurocodes.
Prerequisites
- The course requires the following basic knowledge:
Methods of structural analysis and structural safety evaluation; Non-linear analysis of structures; Design of steel and reinforced structures for ordinary and seismic forces. Course programme
- The course includes 60 hours of lesson, of which 40 lecture hours and 20 training hours. The lectures (40 hours) focus on the following topics:
- Displacement-Based Design - DBD (10 hours)
- Base isolation Design - BID (10 hours)
- Energy Dissipation Design - EDD (10 hours)
- Design of local strengthening with fiber-reinforced composite materials with polymeric matrix (FRP) of structural elements (reinforced concrete beams, columns, and joints) and non-structural elements (masonry infills). Classification of the seismic risk of buildings according to the Sismabonus Guidelines (10 hours)
The training (20 hours) consists of the seismic retrofit design of an existing construction with a steel or reinforced concrete structure, by applying the advanced seismic protection techniques studied during the course. The structural check of the design is carried out by non-linear dynamic analysis methods using a commercial code of finite element numerical analysis. Didactic methods
- The course is constituted of lectures and training hours. During the lecture hours, the theoretical aspects of advanced seismic design are presented. During the training hours the same methods are applied to develop the seismic retrofit design of an existing building. A real case is assigned to students to be addressed individually.
Learning assessment procedures
- The purpose of the final examination is to assess the competence reached by the student in the learning objectives described above. The exam involves the assessment of skills and knowledge acquired by oral presentation and discussion of the project developed during the course. The exam is evaluated with marks within the range of 18 to 30 out of 30.
