Seismic Stability of St. Stephen Hydropower Plant, South Carolina

Abstract

A performance-based analysis was used to assess the seismic performance of St. Stephen Powerhouse erection bay. Two site-specific design response spectra were used to evaluate the structure. These included a 2,475-year probabilistic earthquake event and a deterministic Maximum Credible Earthquake plus one standard deviation event. The St. Stephen Powerhouse superstructure is vulnerable to collapse for earthquake hazards with return periods greater than 500 years. The structure does not meet the basic safety objective (collapse prevention) of the Federal Emergency Management Agency "Prestandard and Commentary for the Seismic Rehabilitation of Buildings," FEMA 356-357.
