Why wait for an earthquake to test building guidelines, construction techniques and retrofit technology when you can simulate earthquakes on an enormous shake table so MASSIVE NASA could launch a space ship from it?
Don’t be fooled, this is no launch pad:
You are looking at the USA’s largest shake table (specs). With a 400 ton payload this 7.6 by 12.2 meter table can move at a peak acceleration of 1.2 g and a peak velocity of 1.8 m/s.
This week Colorado State University engineering professor John van de Lindt and the Network Earthquake Engineering Simulation (NEES) consortium are gearing up to shake a 4 story, 44,000 square foot wood-frame building retrofitted to FEMA P807 guidelines to the ground. The building has already survived 3 tests, one at 1.1 g. Professor Lindt and company have been funded by the National Science Foundation (NSF) of the USA to test cross laminated timber and fluid damper retrofits- think pogo sticks or car shocks for buildings. Tune in and watch 1.24 million NSF dollars collapse on August 17th at Lindt’s YouTube Channel.
For a really spectacular video about a even bigger wood-frame shake table test at the world’s largest shake table facility in Japan see this video by Simpson Strong Tie.
