Quantitative Estimation of Basin Effects Based on Statistic Analysis
Abstract eng: Basin effects have been proven to be of significance to seismic ground motion by many researchers, yet 1D site response analysis, especially based on equivalent nonlinear method, has been dominating in engineering practice. With the aim of contributing to the incorporation of complex site effects into seismic provisions, quantification of 2D basin effects for shallow basins is conducted in this research based on statistics-based numerical analysis to a total of 50 vertically heterogeneous basin configurations subject to real earthquakes recorded on rock sites across the world. It is concluded that for a shallow basin, calibration to the acceleration spectra is only needed to locations within the close-to-edge region of which the width is linear correlated to the basin depth by a factor between 1.2 and 1.5.
