Lower cost shaking tables for safer building and safer cities

 A novel multi-directional simulated earthquake shaking table at a much lower price than current tables!

This invention is available under licence for free

Developed within the school of Civil Engineering at UNSW, this invention is a new type of shaking table used to simulate earthquake ground motions and enable controlled testing of models. This novel design uses two actuators with the same horizontal alignment to simultaneously shake in one horizontal direction and vertically at a much reduced price of the more complex tables currently on the market.

Key benefits

Shaking tables must be anchored to a specially designed and constructed footing embedded in the laboratory floor. Two problems are solved by this technology: 

  1. The use of just two actuators to cause simultaneous vertical and horizontal motion, minimising the cost (as cost is generally proportional to the number of actuators needed).
  2. The avoidance of an expensive foundation system.

Potential applications

The simplest and least expensive shaking tables can shake in one horizontal direction only and require a simple and easy to construct concrete footing that is level with the laboratory floor. There are many more advanced shaking tables around the world which shake in multiple directions simultaneously but involve multiple actuators and very expensive footings.

This technology is suitable in both pricing and functionality for both of these markets.

Opportunity

This technology is available for free as an Easy Access IP Licence. UNSW is seeking a partner to license this technology or to work with the researchers to further develop this technology
