Third experiment in University of Nevada, Reno series uses innovative materials and construction After a succession of eight separate earthquake simulations, a 110-foot long, 200-ton concrete bridge model at the University of Nevada, Reno withstood a powerful jolting, three times the acceleration of the disastrous 1994 magnitude 6.9 Northridge, Calif. earthquake, and survived in good condition. "This is very satisfying to see how well the design and components worked," Saiid Saiidi, principal...

New hybrid technique is safer, far less expensive than shake table testsIt takes just seconds for tall buildings to collapse during powerful earthquakes. Knowing precisely what's happening in those seconds can help engineers design buildings that are less prone to sustaining that kind of damage.But the nature of collapse is not well understood. It hasn't been well-studied experimentally because testing full-scale buildings on shake tables is a massive, expensive and risky undertaking.That's...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary.
