Experimental methods suitable for either overall or parametric seismic performance evaluation of lifeline systems are summarized. Ground motion characteristics, called the most influential parameter of all lifeline systems, are examined. Active field testing methods, passive field testing methods, and laboratory testing methods of below-ground systems are described. Parameters of importance to buried lifeline systems, such as lateral and longitudinal soil resistance characteristics and joint resistant behavior, are discussed. For above-ground lifeline systems, seismic observations, field testings, and model testing of bridges, above-ground pipelines, and communication lifelines are presented. It is said that above-ground lifeline systems can be evaluated by a multiple system table system; such a system is not yet available in the United States.
