Nevada Lab: Quake-Resistant Bridge Design Tests Well

Scientists at a Nevada earthquake lab Wednesday tested new bridge designs with connectors they say are innovative and created to better withstand violent temblors and speed reconstruction efforts after major quake damage. University of Nevada, Reno engineers performed the experiments on a giant “shake table” to simulate violent motions of an earthquake to rattle a 100-ton (91-metric ton), 70 foot (21-meter) bridge model to determine how well it would hold up. The tests, conducted a day after a big quake struck Mexico, shook large concrete columns and beams back and…
