Benchmark tests for strong ground motion prediction methods: Case for stochastic green's function method (part2)

Abstract

We performed a benchmark tests for the strong motion prediction methods using stochastic Green's function method. In addition to the previous paper (Part 1), frequency dependent radiation coefficient of the source and oblique incidences of both SH and SV waves are newly considered. All the results calculated by four teams generally show good agreement to each other, although the analytical conditions are more complicated than the Part 1 paper. Since random numbers are used in generating time histories, synthesized amplitude shows variation in particular frequencies. When applying the stochastic Green's function method, this variation should be in mind.
