Systems analysis for Memphis light, gas and water

ABSTRACT

In this study, a coordinates systems approach was used to examine the overall seismic perfomance of MLGW's lifeline systems. The study examined seismic hazard and ground motion characteristics of the area; geotechnical features, with a special emphasis on liquefaction and resulting lateral spread; the effect of ground motion and geotechnical features on the seismic perfomance of mechanical and structural components including pipelines, storage tanks, pumping stations, treatment facilities, etc., measured in terms of fragility quantities; reliability and interactive nature of system functionality under severe seismic conditions with the aid of Monte Carlo techniques utilizing component fragility information; and the socioeconomic impact arising from system failure.(AU)
