Can site response be predicted
WebApr 5, 2024 · Site conditions, including geotechnical properties and the geological setting, influence the near-surface response of strata subjected to seismic excitation. The geotechnical parameters required for the design of foundations include mass density ( ρ ), damping ratio ( βs ), shear wave velocity ( Vs ), and soil shear modulus ( Gs ). WebAug 10, 2010 · If quantitative estimates of the seismic properties do not exist at a location of interest then the site response spectral amplifications must be estimated from data collected at other locations. Currently, the most common approach employs correlations of site class with maps of surficial geology. Analogously, correlations of site class with …

WebAug 4, 2024 · If the predicted and true responses differ substantially — at least for some observations — the RMSE will be large. A value of zero would indicate a perfect fit to the data. Since the RMSE is measured on the same scale, with the same units as y, one can expect 68% of the y values to be within 1 RMSE — given the data is normally distributed.
