Abstract

ABSTRACT In this paper, we use the BSSA14 model which based on the Wenchuan earthquake data in the NGA-West2 released by the Pacific Earthquake Engineering Research Center in 2013, to study the impact of basin effect on response spectrum.Then we fit the basin coefficients under different site conditions (Vs30=365 and 760 m/s)are fitted, and summarize the relationship between basin coefficients and basin depth parameters. There is evidence that the basin has different effects on long-period ground motion under different site conditions, but the amplification coefficient of the basin increases with increasing depth.
