We have now been carrying out soil structure interaction analyses for over fifteen years using the CLASSI technique. This program was developed by Wong and Luco in the early 1980’s and offers a computationally efficient way of analysing soil structure interaction problems. The soil is represented using boundary elements and structures are represented using finite elements. Multiple foundations can be represented and the interaction between them determined, either as a result of external loads such as earthquakes or local loading such as trains passing.
If you require any assistance with carrying out soil structure interaction analyses using Win-SSI we offer a consultancy service on an hourly, daily or fixed price basis. We are happy to either assist you in understanding and using Win-SSI or we can run your soil structure interaction problem in house.
