- Abstract
- One dimensional site response analysis is widely used in practice to estimate the seismic site amplification effects. The site response analysis involves determination of various uncertainties, which include characterization of future seismic event and dynamic soil properties. The accuracy and reliability of the site response analysis depend on how these factors are properly defined. A site response analysis round robin test has been performed in Korea to evaluate the dispersion of the calculated site responses caused by such uncertainties. To simulate the common practice, only the SPT, CPT data, and boring logs were given for three sites. Three input motions representative of the seismic hazard with a return period of 1000 years were given. The participants were then asked to choose a method of analysis and submit the calculated responses. The submitted results showed significant variation. Among the factors influencing the response, the shear wave velocity had the greatest influence on the dispersion, followed by the dynamic curves, and the type of analysis.
