The indirect boundary element method (IBEM) was established to solve the problem of 3-D seismic responses of 2-D topographies, by calculating the free-field responses with the direct-stiffness method and simulating the scattering wave fields with the dynamic Green's functions of moving distributed loads. The proposed method yields accurate results, …
