Description:
Abstract The electrical equipment has a large quality proportion, and the interaction between equipment and structure cannot be ignored, especially under seismic loads. A 1/25 scale model was designed and made for shaking table test to study its seismic performance, and the acceleration and displacement responses of soil, structure and equipment under unidirectional and bidirectional ground motions were analyzed respectively. The test results show that the acceleration response of the structure and soil increases gradually from bottom to top under the soil-structure-equipment interaction. The acceleration response of equipment is greater than that of the floor where it is located, and it is greater at the position of the side column than that at the position of the central column. The acceleration amplification factor of the soil adjacent to the structure is much larger than that of the soil far away from the structure relative to that at the bottom of the layered shear box.
