Fragility Analysis of Water Supply Systems

摘要: This report describes a procedure to assess the seismic performance of water supply systems. Seismic hazard models are developed generate random samples earthquake activity at both single and multiple sites. Methodologies obtain fragility given pipeline developed, including several conditions: continuous jointed pipelines subjected waves, PGD hazards, fault displacements. Fragility information for other components system is obtained from published sources. These parameters integrated into an algorithm that uses Monte Carlo simulation determine damage states individual components, hydraulic analyses estimate damaged system. The applied sample system, consisting reservoir, pump, tank pipelines, curves produced under different limit states. In addition, life cycle presented. Since each type associated with cost, total cost due hazards during its lifespan can be estimated.
