3D Underwater Shaking Table

Dynamic interaction between soil, structure and water influences behavior of on/offshore facilities such as quay walls, breakwaters and seawalls during earthquakes. To investigate the seismic performance of those facilities, the underwater 3D shake table is employed. The circular shake table of 6m in diameter is installed in the bottom of a square pool 13m long and 2m deep. The shake table has two horizontal and one vertical axes with a maximum displacement of ±30cm, and a maximum acceleration of 2G.
