Course unit contents: - Basis of seismology. Earth structure, seismic waves, plate tectonics, faults. Elastic-rebound theory and seismic-gaps. Non-tectonic earthquakes. Intensity and magnitude of an earthquake. Parameters of seismic shaking and seismic hazard assessment.
- Seismic risk. Definition of hazard: origin, intensity and classification of earthquakes; site effects; induced and activated seismicity. Definition of exposure, costs and malfunctioning related to damage to non-structural components (infill walls, false ceiling, installation, art objects, etc). Seismic vulnerability of reinforced concrete and masonry buildings. General criteria for aseismic design and modelling of structures. Seismic action and buildings performance related to code prescribed limit states. Diplacement-Based Design and Assessment.
- Criteria for the classification of seismic vulnerability of existing buildings for the assessment of seismic risk. Application to single buildings (with reference to the sisma-bonus) or for the management of seismic risck at territorial scale (public authorities).
-Introduction to the dynamics of base-isolation systems. Aseismic devices: seismic isolation and dissipative systems. Principal requirements for modeling and analysis of isolation systems (NTC08, EC8). Example of design of buildings with base isolation. Seismic protection of the contents (objects and installations). Principles of inter-storey isolation and additional damping for medium-high rise buildings.
- Seismic vulnerability assessment, inspection on structures, improvement/upgrading interventions on existing buildings. Code approach to existing buildings, knowledge levels and confidence factors. Strengthening techniques and verification methods for RC and masonry buildings with traditional and innovative materials ( FRP, FRG, SRG, TRM…), also in relation to case-studies
- Numerical methods for static and dynamic analysis of structures and applications with software codes. Introduction to Building Information Modeling (BIM) for applications to structural engineering and aseismic design.
