This report presents the results of an investigation into the behavior of a complex spatial piping system under simulated seismic and thermal loading. The control of seismic response by steel energy absorbing devices is studied and compared with equivalent response controlled by shock arrestors. The concept is based on previous work on booth plane and spatial piping systems. The specimen selected for study was a half-scale model of a piping system from a nuclear reactor power plant. This was tested in its original design configuration using mechanical shock arrestors (snubbers), and subsequently in a revised configuration using ductile steel energy absorbers. The influence of the snubbers and of different energy absorbers on the dynamic response of the pipe system is discussed in this report. A direct one-to-one replacement of the snubbers by energy absorbers allows a direct comparison of the results.
