World’s largest earthquake simulator upgraded to improve tall structure safety
The world’s largest outdoor earthquake simulator is undergoing a major upgrade to improve safety tests for tall structures.
When completed this autumn, the simulator will have the ability to reproduce multi-dimensional earthquake motions with unprecedented accuracy to make structures and their residents safer during strong shakes.
The simulator, or shake table, will be able to test the world’s heaviest and tallest structures to gauge how well they would withstand various types of earthquakes. The shake table will be equipped with the ability to reproduce all the six possible movements of the ground, known as six degrees of freedom.
A major upgrade to the world s largest outdoor earthquake simulator reached a milestone mid-April when the facility s floor all 300,000 lbs of it was put back into place. When completed this fall, the simulator will have the ability to reproduce multi-dimensional earthquake motions with unprecedented accuracy to make structures and their residents safer during strong shakes. Researchers lay out the details of the upgrade in a paper published in January 2021 in Frontiers in Built Environment.
