- The goal of the research was to develop a design methodology, including practical guidelines, to seismically protect hazardous piping systems. Existing documents applicable to seismic design, piping systems, and hazardous materials classification were identified and reviewed. Specific design criteria were delineated and included categorization of piping system importance, quantification of earthquake hazard and vibratory environment, and specification of allowable stresses. These criteria were used to develop tentative design requirements which specify acceptable methods for determining seismic restraint of hazardous piping. Analytical models of polyvinyl chloride and steel piping systems, typical of systems found in industrial facilities, were analyzed to evaluate the tentative design requirements for various seismic bracing schemes.
