earthquake shaking table japan

The shaking table can subject structures, weighing 100,000 lbs, to horizontal accelerations of 1.5 G. The concrete shaking table is heavily reinforced with both traditional reinforcement and post-tensioning tendons. Structurally, the table may be considered as a 1′ thick diaphragm, stiffened by heavy central transverse ribs that extend below its bottom surface. The hydraulic actuators that drive the table …
