The 25th anniversary of the M6.9 Loma Prieta earthquake in northern California was recognized around the country Oct. 17, 2014. The University of Nevada, Reno fed the recorded information from the epicenter of the earthquake into its earthquake simulation software, which generated dramatic motions to their 14- by 14-foot shake table in its earthquake engineering lab. the building and contents on the table shook violently, mimicking the deadly earthquake. the shaking in the first part of the video is 100 percent acceleration and intensity at the epicenter on the ground floor. The second portion of the video simulates 100 percent of the earthquake as it would be on the 10th floor. The demonstration in the University’s world-renowned Earthquake Engineering Lab helps people understand the impo...
(21 Sep 2017) A day after a deadly earthquake struck Mexico City, University of Nevada, Reno, scientists have tried to mimic an earthquake in a lab to test new bridge designs developed to help the structures better withstand violent temblors. The engineers on Wednesday rattled a 100-ton, 70-foot (21-meter) bridge model to see how it held up on a giant contraption in a Reno seismology lab called a "shake table." The design has flexible columns and reinforcement bars made out of a metal alloy that bends and then springs back into shape when quakes hit. Bridges are already designed not to collapse in earthquakes but often are unsafe for travel after the disaster. The research team's leader, Professor Saiid Saiidi, said the innovations in the model being tested involve connections and mate...
The College of Engineering at the University of Nevada, Reno moved three of its four 14 by 14 foot, 27-ton shake tables used to simulate earthquakes in its world-renowned civil engineering lab. Large-scale models of structures are placed on the tables to test new designs and new materials to make buildings, bridges and highways safer. http://nees.unr.edu.
The University of Nevada, Reno's impressive Large-Scale Structures Earthquake Engineering Laboratory contains a 145-foot-long, 162-ton steel and concrete bridge that was built atop four large, 14-foot by 14-foot, hydraulic shake tables. The unique lab enables the engineers to simulate large earthquakes. You can find more about the lab here: http://www.sciencenewsblog.com/blog/923112

In most states the process of starting a business is encumbered by paperwork. Dozens of forms that need to be physically filled out and filed with state agencies. With the help of the Law Lab, a project of the Berkman Center for Internet & Society at Harvard University, Nevada has launched a one-stop e-portal for filing and operating a business.

Nicknamed "Leda," it provides key data for Stockpile Stewardship. Los Alamos National Laboratory has successfully fired the latest in a series of experiments at the Nevada National Security Site (NNSS). This video shows the Leda containment vessel in the "zero room" at the U1a underground complex at NNSS. The experiment is fully contained inside the vessel. The experiment, conducted on Aug. 12, 2014, consisted of a plutonium surrogate material and high explosives to implode a "weapon-relevant geometry." Hydrodynamic experiments such as Leda involve non-nuclear surrogate materials that mimic many of the properties of nuclear materials. Hydrodynamics refers to the physics involved when solids, under extreme conditions, begin to mix and flow like liquids.
