soil structure interaction

[liuza]

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

do you find any thing?

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
