Fundamentals of Earthquake Engineering‎:‎ From Source to Fragility‎,‎ Second Edition combines aspects of engineering seismology‎,‎ structural and geotechnical earthquake engineering to assemble the vital components required for a deep understanding of response of structures to earthquake ground motion‎,‎ from the seismic source to the evaluation of actions and deformation required for design‎,‎ and culminating with probabilistic fragility analysis that applies to individual as well as groups of buildings‎.‎ Basic concepts for accounting for the effects of soil‎-structure interaction effects in seismic design and assessment are also provided in this second edition‎.‎ The nature of earthquake risk assessment is inherently multi‎-disciplinary‎.‎ Whereas this book addresses only structural safety assessment and design‎,‎ the problem is cast in its appropriate context by relating structural damage states to societal consequences and expectations‎,‎ through the fundamental response quantities of stiffness‎,‎ strength and ductility‎.‎
