The subject of the course is Earthquake Engineering with special reference to the design of earthquake resistant structures.
The first part (first semester) focuses on the design of building structures for earthquake resistance (Eurocode 8 – Part 1). The following topics are discussed:
1. Fundamentals of seismology: seismic wave origin and propagation; surface motion description and effects.
2. Main concepts from structural dynamics:
- SDOF systems and seismic action: the response spectrum;
- MDOF systems: modal analysis and its application to frame structures.
3. The linear analysis of frame structures: equivalent static analysis versus dynamic modal analysis, code requirements, computer codes.
4. The non-linear response of structures: ductility, the behaviour factor theory, local ductility demands, collapse mechanisms, structural regularity. Modern code requirements (EC8, Italian Code).
5. Design of concrete structures: structural typologies and behaviour factor values, specific rules for the design of beams, columns, shear walls, joints.
6. Design of steel structures: structural typologies an behaviour factor values, specific rules for the design of details.
The second part of the course (second semester) is devoted to the discussion of both special problems and special structures. The main topics are:
1. the push-over analysis (static non-linear analysis);
2. base isolation and energy dissipation;
3. amplification of seismic motion in relation to local soil conditions;
4. soil-structure interaction;
5. general rules for the analysis and strengthening of existing structures;
6. masonry structures: characteristics, analysis tools, structural details.
7. Bridge structures and other special structures (silos, tanks, chimneys, …)
