What is the appropriate distance between the side boundaries in a 3D numerical model of a soil-structure interaction system for a seismic analysis?

For instance, Rayhani and El Naggar (2008) posited that the said distance ought to be greater than five times of the superstructure width. Rayhani, M. H., & El Naggar, M. H. (2008). Numerical...
