The horizontal amplitude screening effects of an in-filled trench are solved using the boundary element method in the frequency domain. Dimensionless parametric studies are performed to assess the screening effects of the trench in terms of the geometry, in-filled material, foundational embedment, and shear wave velocity ratio of the in-filled material to the surrounding soil. The results show that the screening effects of the in-filled trench depend highly on the trench geometry and the velocity ratio of the in-filled material to the surrounding soil. The embedment ratio of the foundation and other factors are relatively unimportant.
