Analysiso f data from strong motion network in fraser delta, british columbia, canada

摘要

The 1996 Duvall earthquake in Washington State triggered ground motion stations in the Fraser Delta, British columbia, Canada. Recorded ground motions were used to examine the applicability o 1-D and 2-D site response analyses for amplification studies in the Delta. 1-D response analysis gave a good indication of the period of peak response, but response spectra were generally not satisfactory for engineering purposes. The use of 2-D analyses which included buried topography generally improved the predictions of site response spectra.
