Seismic piping test and analysis

This report presents selected results to date of a dynamic testing and analysis program focusing on a piping system at Consolidated Edison Company of New York's Indian Point-1 Nuclear Generating Station. The goal of this research program is the development of more accurate and realistic models of piping systems subjected to seismic, hydraulic, operating, and other dynamic loads. The program seeks to identify piping system properties significant to dynamic response rather than seeking to simulate any particular form of excitation. The fundamental experimental approach is the excitation of piping/restraint devices/supports by a variety of dynamic test methods and the analysis of the resulting response to identify the characteristic dynamic properties of the system tested. The comparison of the identified dynamic properties to those predicted by alternative analytical approaches will support improvements in methods used in the dynamic analysis of piping, restraint, devices, and supports
