Although the course “099243 - EARTHQUAKE RESISTANT DESIGN (I.C.)” is constituted by two modules ( Earthquake Resistant Design 1 and 2 ), these are fully integrated and both spread over the two semesters. The following list of topics corresponds to the total contents of the integrated course.
First part : Design of new building structures for earthquake resistance.
Seismic action definition:
- fundamentals of seismology: seismic wave origin and propagation; surface motion description and effects;
- seismic response of SDOF systems: the response spectrum;
- linear response of buildings to the seismic motion:
- modal analysis of frame structures;
- structural modelling for seismic analysis: mass and stiffness representation;
- linear analysis of frame structures: static equivalent, modal, and time history analysis;
Non linear response of structures:
- the behaviour factor theory;
- global and local ductility demands;
- global and local collapse mechanisms and capacity design;
- structural regularity;
- response computation: non-linear static analysis.
Design of buildings for seismic actions:
- reference building codes: Eurocode 8 (Part 1), Italian Code (NTC-08);
- general requirements for the design of building structures;
- concrete structures: structural typologies, behaviour factors, specific rules for the design of structural elements (beams, columns, nodes, walls);
- steel structures: structural typologies, behaviour factors, specific design rules, action modification in the capacity design.
- criteria for the sizing of buildings under seismic actions.
Numerical analysis of buildings for seismic actions:
- finite element analysis by commercial codes;
- comparison between experimental and numerical response of structures;
- analysis and design of typical frame buildings.
Second part : Special problems and special structures.
Base isolation and energy dissipation;
Amplification of seismic motion in relation to local soil conditions;
Seismic response of existing structures: knowledge levels and confidence factors;
- material properties and resistance;
- box-type behaviour;
- response computation (global shear resistance, collapse mechanisms, refined analysis);
- structural details and strengthening interventions;
- vulnerability analysis;
- guide-lines for monumental structures (churches and palaces).
Special structures (bridges, silos, …).
