DEP 514E – Seismic Hazard Assessment

The content of the course includes the Maximum Considered Earthquake (MCE) and Design Basis Earthquake (DBE) concepts, Guttenberg-Richter law, earthquake catalogues, available source models, ground motion prediction equations, terms that help in connecting the fault activity to design basis spectrum. Seismic Hazard Assessment (SHA) methods, both semi- deterministic and probabilistic, and supporting examples and exercises are examined in the course. Details in Probabilistic Seismic Hazard Assessment (PSHA), treatment of uncertainty in SHA issues will be covered. The course will culminate with the elaboration of the subject on the determination of the Design-basis Ground Motion (DGM) needed for the code-based and performance-based design of engineering structures. The content will be particularly useful in design of tall structures, critical facilities or other structures where a controlled seismic performance is expected.

Engineering Seismology & Seismic Hazard Assessment

(@ UME School, Pavia, Italy)

This is an introductory course on the fundamentals of engineering seismology, strong ground motion and seismic hazard assessment. The ultimate object is to provide a background for the assessment of design- basis ground motion both in frequency and time domain. This will be achieved with formal lectures themselves, tutorial sessions and the practical exercises. These teaching activities will be supported with power point presentations, textbook chapters and relevant papers and Internet web sites. This material should be sufficient to obtain a basic background on the subject and to pave the path for those seeking a deeper understanding or greater detail. The course will encompass the basic treatment of the physics of earthquakes and analysis of wave propagation. The time and frequency domain characteristics of the strong ground motion will be covered with enough detail to facilitate the understanding of ground motion prediction and the earthquake hazard assessment. The probabilistic and deterministic treatment of seismic hazard will be covered with supporting examples and exercises. The course will culminate with the elaboration of the subject on the determination of the design basis ground motion needed for the code- based and performance-based design of engineering structures.
