Yossef, I would recommend that you look online for some accepted methods for dealing with ground coupling. I have seen the method that you suggest used but I have not seen any technical papers that present its results against an analytical solution or against measurements. The simplest method of which I am aware is the "f factor" approach. There is also a Type in the standard library (Type49) that couples a building to the ground through a slab. Another (Type1267) is available as an add-on for more complex building geometries that cannot be handled by Type49. kind regards, David
