| Description: | Technical report Abstract: This report addresses the effect of different idealization schemes on calculated dynamic site response analyses. The two methods compared were the "individual column" and the "best estimate" methods. The "individual column" method uses several unique individual soil columns, each developed from specific subsite data. The "average column" method involves averaging information from each subsite into one idealized representation. Use of the "average column" method typically involves a parametric analysis of model parameters, mOst importantly, shear modulus. This report compared these methods for two projects site: DOE Portsmouth Gaseous Diffusion Plant and DOE Savannah River Site. The results of the two idealization schemes are also compared with measured variations of ground motion response during earthquakes. In general, the two idealization sehemes produced similar results for the shallow site, despite a relatively large variation in depth to rock, and substantially different results for the deep site which was assumed to have a constant depth to rock. |
