Civil engineers using a specialized laboratory at Purdue University have demonstrated the effectiveness of a simple, inexpensive method to strengthen buildings that have a flaw making them dangerously vulnerable to earthquakes.The flaw is widespread in China, Latin America, Turkey and other countries.

By Tu-Uyen Tran, Grand Forks Herald, N.D. Jun. 24--Under the Sorlie Bridge in East Grand Forks, rust patches the steel beams that support the road above, which, during most of the day and night, rumbles with passing traffic. But for bridge inspector Jeff Moore, the rust isn't a big deal because as long as it's just cosmetic, it won't have any impact on the strength of the beams. "Paint makes it look worse than it is." With funding from the Minnesota Department of Transportation, he and...

By O'Ryan Johnson, Boston Herald Jun. 20--The green hulk in Boston Harbor known as the Tobin Bridge is getting a $1 million early warning system to detect structural failures in the millions of tons of steel and concrete before it buckles and cars plummet into the Mystic River. A Burlington company was awarded a contract yesterday to complete initial testing of the bridge, then begin installing the wireless stress sensors on some of the steel beams used to prop the two-mile long behemoth...

SAN DIEGO (AP) -- A blast simulator that can deliver the same punch as a car bomb was unveiled Wednesday in a laboratory at the University of California, San Diego, as part of a federal anti-terrorism program. The device uses heavy rubber pads driven by hydraulic pistons to create the same split-second effects that explosives would have on columns, beams, floors, ceilings and girders, school officials said. The $10 million simulator will be used to develop ways of hardening buildings and...
