Substructuring for Soil Structure Interaction Using a Shaking Table …
Abstract. The experimental investigation of soil-structure interaction (SSI) phenomena is typically performed on a shaking table with a model foundation-structure system embedded in a soil container. As the size and power of the shaking table limits the size of the specimen, only small scale models can be tested using this method.
