dc.descriptionAbstract: This report summarizes the results corresponding to a series of dynamic stress analyses performed on an overflow and a nonoverflow monolith of Folsom Dam, California. The monoliths selected for analysis were monoliths 14 and 21, and they were chosen as representative of critical overflow and nonoverflow configurations. The analyses were conducted using the computer program EAGD-84, developed by Professor A. K. Chopra and co-workers at the University of California at Berkeley. The analyses accounted for dam-foundation interaction and water compressibility effects, and considered two loading scenarios: (A.) horizontal component of the ground motion and (B.) horizontal and vertical components of the ground motion. The results are reported in terms of the maximum expected stresses under extreme loading conditions (maximum credible earthquake, MCE), and they are compared with those results obtained from analyses performed by engineers at the Sacramento District using a response-spectrum-based procedure also developed by Professor Chopra. The influence of the vertical component of the ground motion on the magnitude and distribution of the dynamic stresses is investigated. The levels of tensile demands predicted by this study indicate that localized damage in the form of tensile cracking is likely to take place in limited areas of monoliths 14 and 21 when subjected to extreme seismic loading, but this is still acceptable seismic performance under MCE conditions.-
