What does a shake table do?

What does a shake table do?

A shake table simulates the ground motions that take place during an earthquake. They’re used to test structural models, scaled slopes, or building components, typically to the point of failure.

How much does a shake table cost?

The cost of the table is about US$45,000, which is approximately half of the global marketing price of a single-axis shake table that can handle a test payload of about 1000 kg.

Who invented the shake table?

University of Tokyo
While modern tables typically consist of a rectangular platform that is driven in up to six degrees of freedom (DOF) by servo-hydraulic or other types of actuators, the earliest shake table, invented at the University of Tokyo in 1893 to categorize types of building construction, ran on a simple wheel mechanism.

Why do scientists use shake tables?

For testing purposes, engineers design shake tables to simulate (or re-enact) the seismic waves produced by earthquakes and verify the stability and survivability of their structures.

How can you simulate an earthquake at home?

Evenly place the rubber bands around the two pieces of cardboard. Squeeze the marbles in between the two pieces of cardboard as evenly distributed as possible. If you tug on one of the cardboard pieces, it should shake. You now have your earthquake simulator!

How do you build a earthquake proof house for a school project?

How to Make A Building Earthquake-Proof

1. Create a Flexible Foundation. One way to resist ground forces is to “lift” the building’s foundation above the earth.
2. Counter Forces with Damping.
3. Shield Buildings from Vibrations.
4. Reinforce the Building’s Structure.
5. Steel and Wood.
6. Innovative Materials.

How do you simulate an earthquake?

How might other science and engineering fields use a shake table?

Well, engineers create shake tables to test the ability of buildings and other structures to withstand the seismic waves produced by earthquakes. To do this, they carefully design and construct shake tables that can accurately re-enact the ground motion of the Earth during earthquakes.

What is the purpose of the shaking table at UC Berkeley?

The table has been pivotal in proof-of-concept tests for energy dissipation devices and building systems, as well as anchoring and bracing systems — leading to improved construction standards and technologies.

What does shake table mean?

What does shake table mean? Here are all the possible meanings and translations of the word shake table. Did you actually mean suggestible or sheath pile? An experimental platform that simulates earthquake motion to verify seismic performance of building structures. How to pronounce shake table?

How many types of shake tables are there?

All three tables can be constrained to act together as a single large table, or they can be operated individually with independent motions. We also have a fourth shake table referred as the 6-Degree-of-Freedom (6DOF) table. The fourth table is a true 6 degrees of freedom system, with three translational and three rotational components.

How does the Shake Table II work?

The Shake Table II consists of a top stage driven by a powerful motor that allows it to achieve an acceleration of 2.5 g when loaded with a 7.5 kg mass. The stage has a travel of 15.2 cm and rides on two ground-hardened metal shafts using linear bearings, which allows for smooth linear motion with low path deflection.

How is the acceleration measured on the Shake Table II platform?

An analog accelerometer mounted on the Shake Table II platform measures the acceleration of the stage directly. ¹ Please contact Quanser for full operational bandwidth specifications.
