We present a hybrid shaking table test algorithm that can be used for the investigation of earthquake response of structures taking account of the soil-structure interaction effects but without using a physical soil-box. The base motion of structures, the table motion, accounting for soil-structure interaction effects is obtained computationally and is provided as the table motion for the test of a structure model. At each instance of time the table motion is predicted and at next instance corrected using the measured acceleration responses of the structure model. With this algorithm only the structural part of the whole SSI system needs be tested on a shaking table. The validity of the proposed algorithm is examined through numerical examples and laboratory shaking table tests. |
