This volume presents recent advances in research, practice, post earthquake investigation, and public policy in lifeline earthquake engineering as a discipline and as a component of infrastructure rehabilitation. Written by utility engineers, consultants, managers, and transportation agency personnel from various nations, papers review newer emerging topics of lifeline interaction and socio-economic effects, as well as hazard assessment methods, analysis procedures, and design approaches. Topics range from bridge analysis and rehabilitation to bridge earthquake damage assessment, electric power and communications to gas and liquid fuels. Case studies and papers detail the seismic assessment of offshore pipelines; above ground pipeline response to random ground motion; bridge prioritization for emergency responses; inspection and rehabilitation of tunnels across faults; and spectral characteristics of vertical ground motion in the Northridge and other earthquakes.
