Use of base isolation and energy-absorbing restrainers for the seismic protection of a large power-plant component. Final report. [PWR]
Analysis of the seismic response of large components in power plants is complicated by interaction between the component and the structure. In large components such as the steam generator this interaction cannot be neglected in forming accurate estimates of the response. Further, the presence of cracks in the internal piping of some steam generators has led to their integrity under seismic action being questioned. The experimental program described herein was initiated by the Electric Power Research Institute of Palo Alto, California, to provide an experimental assessment of the influence of interaction on the seismic response of such a large component.more »
