Hi
I need an example about 3D soil structure interaction
can any one help me?
Thanks alot

Our approach to regional earthquake simulation
has been to use an innovative multi
-
scale method. The regional
ground motion simulation is uncoupled from the subregional analysis that includes the detailed models of
nonlinear soils, foundations, and building i

To simulate the interaction between a structure and soil you can apply interface elements. Without an interface the structure and the soil are tied together:
no relative displacement (slipping/gapping) is possible between structure and soil. By using an interface, node pairs are created at the interface of structure and soil. From a node pair, one node belongs to the structure and the other node belongs to the soil. The interaction between these two nodes consists of two elastic-perfectly plastic springs. One elastic-perfectly plastic spring to model the gap displacement and one elastic-perfectly plastic spring to model slip displacement. I got essay writing task for this topic as part of my geology studies. I got these kind of useful answer from admission essay writing service @ http://www.clazwork.com/admission-uk-es ... ice-connor
