Fragility Analysis of a water supply system

The seismic performance of a water supply system depends on the individual performance of its components and on system configuration. Components of a water supply system include pipes, tanks, tunnels, reservoirs, and other components. Complete fragility analysis is performed on pipes, including analysis of pipes under seismic wave hazard and fault displacement hazard, two commonly occurring types of hazard following a seismic event. The influence of seismic wave hazard is assumed to be more prominent for pipes located far away from seismic source, while fault displacement hazard is assumed to affect only pipes located on seismic sources, i.e., faults. Fragility information for other components is taken from the literature. Ongoing work focuses on performing Monte Carlo simulation and hydraulic analysis to generate fragility information on a damaged water supply system
