Module general description:

Technical Seismology
Mechanisms of seismic generation. Measuring and recording the seismic motion. Magnitude and energy of seismic motion. Theory of plate tectonics. Seismic source and epicentre. Seismic prediction. Strong ground motions. Site conditions. Amplification and attennation of seismic waves. Near fault and far fault motions. Seismic risk.

Genaration and Propagation of Seismic Waves
Dynamic theory of elasticity. Stress and strain. Hooke’s law between stresses and strains. Equations of motion in terms of displacements. Fracture mechanics of brittle materials and seismic faults. Propagation, reflection and diffraction of seismic waves. Primary (P), Shear (S), Rayleigh (R) and Love (L) waves in the full space or the half-space soil medium under homogeneous or non-homogeneous conditions. Material and geometrical damping in soils.

Dynamics of Soils and Foundations

asic concepts from soil mechanics and wave propagation. Laboratory and field tests for the determination of soil properties. Soil behaviour under monotonic and cyclic shear deformation. Methods for determining the dynamic response of soils and foundations. Seismic motions of soil and site effects. Consolidation and liquefaction of soils. Seismic design of slopes, dams and retaining walls. Seismic design of foundations and piles.

Learning Outcomes:
On successful completion of the module, students will have understood the nature of the earthquakes and the response of soil formations during the seismic motion. In this way, they will be able to assess the seismic risk of civil engineering works, an important issue for the seismic design of structures. More specifically, the following subjects will be studied: the fracture on the causative fault and the generation of the earthquakes; the recording of the seismic motion and the measure of its intensity; the generation and the propagation of the seismic waves; the basic principles of seismic hazard analyses; the seismic response of soil formations; the effect of the ground response on the seismic motion that is applied at the base of the structures; and the seismic design of natural slopes, dams, embankments, retaining walls and shallow and deep foundations.

Subjects covered:

  1. Engineering seismology
  2. Generation and propagation of seismic waves
  3. Seismic response of soils and dynamics of geostructures and foundations

Teaching Method: Distance education with five Contact Sessions held at weekends during the academic year

Evaluation: Completion of five written assignments during the academic year, the average grade of which constitute a 30 percent of each student's grade, if a pass is obtained in the final or repetitive examination. Final exam grades constitute a 70 percent of the students' final course grade. More information is available
