Quantitative Evaluation of Four Kinds of Site Seismic Response Analysis Methods Using DTW

Abstract In order to quantitatively evaluate the one-dimensional site seismic response analysis methods, this article selected 2418 ground motion records of Japan KiK-net strong-motion seismograph network and groups acceleration spectra calculated by DEEPSOIL, SHAKE2000, SOILQUAKE SOILRESPONSE, then` used dynamic time warping (DTW) algorithm calculate DTW distance between measured spectrum spectrum. The average change trend in different PGA ranges were compared analyzed. four methods weak similar, strong motion, SOILRESPONSE was smaller than other three methods. increased with increase PGA, growth rate significantly lower can accurately effectively reflect difference spectrum, which provides a new method for quantitative evaluation method.
