Acerca de este curso

  • Introduction
  • Week 1 - Seismicity and faults
    • The first week allows to discover the Earth structure, the plate tectonics, the behaviour of faults in the crust and the radiation of seismic waves. The seismicity of the Earth is studied and that of Mars is shown as well! The control of faults and the magnetic properties of the Earth are finally explained.
  • Week 2 - Seismic waves and ground motion
    • Various types of seismic waves are presented through both actual observations and theoretical interpretation. Their propagation and amplification in heterogeneous geological structures are discussed (soil layers, alluvial basins). The application to site characterization is finally proposed.
  • Week 3 - Seismic response of soil and structures
    • The seismic soil response is analyzed first. The simplified soil response is then converted into a so-called response spectrum for sake of seismic design. The seismic response of structures is discussed through eigenmodes, modal superposition and modal recombination. Seismic isolation and in situ dynamic characterization of structures is also presented.
  • Week 4 - Complex structures and non linearities
    • Dynamic Soil-Structure Interaction and Soil-Foundation-Structure Interaction are presented first. Typical nonlinear behaviours of structures are then analyzed. The seismic response of structures is finally discussed through simplified (e.g. push-over) and time history nonlinear analyses.
  • Week 5 - Seismic risk
    • Vulnerability and damage assessment are introduced first. They are illustrated for masonry structures in the field and concrete structures on shaking tables. The effect of uncertainties is then discussed in order to derive fragility curves. Finally catastrophe and loss models are explained.
