Abstract:

At the request of the Charleston District, the Engineer Research and Development Center ERDC conducted a seismic stability evaluation of the St. Stephen Hydropower Plant, SC. Enclosure 1 summarizes the details of this seismic engineering evaluation of the powerhouse superstructure. A performance-based approach, as outlined in the FEMA document 356 ref a, was used for the seismic evaluation to determine the risk of the superstructure collapse during a major earthquake. Collapse prevention performance requires that collapse of the structure be prevented regardless of the level of damage inflicted by the earthquake on the superstructure.
