The objective of this book is to present some recent earthquake hazard and vulnerability analysis models for lifeline systems. The approach considered is different from seismic risk analysis of conventional structures in that lifelines are spatially distributed with components exposed to varying hazard levels. Losses to lifeline systems can result from direct damage to components that are affected by a single event or they can be due to down time and unavailability of the product they supply. The emphasis in the papers is on the evaluation of direct losses from failures of various types of systems. Methods for estimating direct losses and treatment of uncertainties are described in two of the papers. The approach considered is general and can be applied to most lifeline systems. Example analyses include water and transportation systems. Several of the papers summarize developments made under the Seismic Risk Assessment Study for Water and Sewage Systems conducted by the Seismic Risk Committee of the Technical Council for Lifeline Earthquake Engineering of ASCE.
