Recent major earthquakes around the world have shown the vulnerability of
infrastructure and the need for research to better understand the nature of seismic
events and their effects on structures. As a result, earthquake engineering research has
been expanding as more and more data become available from a large array of seismic
instruments, large scale experiments and numerical simulations. This book presents
results from some of the current seismic research activities including threedimensional
wave propagation in different soil media, seismic loss assessment,
geotechnical problems including soil-structure interaction, and seismic response of
structural components and structures including historical and monumental structures,
bridge embankments, and different types of bridges and bearings.
First part of the book deals with seismic risk assessment and hazard analysis with a concentration on seismic microzonation, development of probabilistic hazard maps, geotechnical problems including soil-structure interaction, and three-dimensional
wave propagation in different soil media considering different surface characteristics and topography. Chapter 1 provides a methodology for seismic risk assessment within
a performance based earthquake engineering framework. Probabilistic hazard analysis and economic models are used for loss estimation and evaluation of earthquake impact on regional economies. Chapter 2 describes development of seismic
microzonation and probabilistic hazard maps for a specific region. Details of site characteristics including geological conditions and soil nonlinearity were considered
in the seismic zoning and hazard assessment. Chapter 3 presents cognitive methods for modeling geotechnical and seismological problems. New data-driven modern techniques are used to complement and improve the traditional physically-based
geotechnical modeling and system analysis under earthquake loading.
