The LHPOST6 shake table at UC San Diego is raising the bar in earthquake engineering research. San Diego, CA, Jan. 8, 2021 Recently at UC San Diego, two giant cranes lifted the 330,000 lb. steel floor, or platen, off the world s largest outdoor shake table, revealing a complex network of pipes, wires and catwalks.
three-axis shake tables to earthquake simulation. A single-axis shake table that can handle a test payload of about 1000 kg costs about US $120,000 and can be readily purchased in the global market. A three-axis earthquake shake table for the same payload may cost much more *For correspondence, (e-mail: r.sunder@vsnl) than US …

Beneath the table are mechanical devices called actuators that work together to simulate an earthquake. Typically, two actuators shake the table along the X axis, two shake the table along the Y axis, and four shake the tables vertically along the Z axis. The tables can also rotate independently along each of these three axes.

The shake table test results of a high-rising building with large local space show that the dynamic characteristics of such structure are complex and the torsional mode becomes the first mode ...
JOHN DAY, OR – Forest Supervisor, Steve Beverlin, has implemented an area closure, effective immediately, for the West Fork Fire, which is located on the north slope of the …
The first step in designing a full-scale shake table is to understand the ground motions that it must replicate. Professor Toksoz and his coworkers analyzed data on peak ground accelerations (PGAs) measured during 15 significant earthquakes worldwide. (Strong-ground-motion instruments generally measure accelerations; velocities and ...
At the University of California San Diego, there's the Shake Table: an earthquake simulator with the heaviest payload capacity in the world.

The QuanserShake Table III XY consists of a stage mounted on the ground support plate. The stage is actuated by three linear motors and move in either the x or y directions. Two motors mounted on the ground support plate of the table operate in parallel and power the x-axis. A single motor mounted to the stage actuates the y-axis.
Episode 2, June 8: UCSD s Koorosh Lotfizadeh explains the shake table upgrade, which will enable it to shake structures with six degrees of freedom. The newly named LHPOST6 can simulate subtle ground rotations, for example, which will provide new insights on inter-story drift, top-story displacements and the behavior of internal building ...
