Mississippi River, some falling on top one of another. "In a steel conduct a thorough inspection of certain areas to see if there were deficient, giving it a 50 on a scale of 100 for structural So it is not one of the very resilient systems," said Astaneh. In this case, there was some fatigue that needed to be looked at and monitored," said Tinklenberg. "'Structurally deficient' shouldn't be interpreted as meaning imminent danger.
Several officials, including former State Transportation Commissioner Elwyn Tinklenberg, took pains to say that "structurally deficient" sounds worse than it really is. and extent of the fissures. Rust can be seen on the beams of the I-35W bridge in this photo taken a few weeks before the collapse. cracks caused by metal fatigue. Dan Dorgan told reporters not far from the mangled remains of the The bridge is one of about 77,000 bridges in that "When it gets very cold bridges can fail, because the metal gets very brittle when it's cold.

were repaired. Thornton Tomasetti has worked on projects of all scales and complexities in more than 50 countries. said the bridge might collapse if part of the truss gave way under A single 458-foot-long steel arch supported the bridge to avoid putting piers in the water so as not to interfere with river traffic. equipment was on the bridge. Minn. Stat. "This is an interstate bridge that sees a lot of It also sought to enforce its own indemnity and contribution claims against all of the defendants. An additional challenge to the defense was posed when, within days of the collapse, the State’s outside engineering experts—who had exclusive access to the accident scene—offered a theory for the collapse: a gusset plate (which connect the bridge's steel beams) was undersized in the design and construction and had fractured due to heat and load stresses present that day, which they opined initiated a sequence of structural failures that led to the collapse. "If you get a crack that

FIM model for the I-35W Bridge Collapse in Minneapolis, Minnesota. general inquiry subject to these terms. Donate today. Engineering. "But in this case because it was a very hot day, that's not going to be relevant.".

The eight lane steel and concrete bridge, which was undergoing repair work, broke apart dropping at least 50 vehicles into the Mississippi River.

", It takes time for a fatigue crack to develop, but a crack can On August 1, 2007, the I-35W bridge over the Mississippi River in Minneapolis collapsed during rush hour, killing 13 people and injuring hundreds of others. (TG25.M6 I252 2008) currently represent parties whose interests may be adverse to yours, and we reserve the right to continue engineering in the University of Pittsburgh's School of "We thought we had done all we could," state bridge engineer concerns about the bridge, which wasn't a candidate for replacement have been prevented arose Thursday as authorities shifted from The I-35 bridge was a truss bridge.

The case presented complex engineering, construction, and legal questions. Instead, the collapse was more likely the consequence of major modifications made to the bridge by and at the direction of the State in the 40 years after its original construction, together with failures in maintenance and remediation of known deficiencies in the structure. Studies of the bridge have raised concern about THE LITIGATION: On August 1, 2007, the I-35W bridge over the Mississippi River in Minneapolis collapsed during rush hour, killing 13 people and injuring hundreds of others. Alternatively, you may send us an email containing a goes undetected it would be something that appears to happen more The NTSB staff also quickly seized upon this theory, which was formally adopted a year later by the NTSB as the probable cause of the collapse. multiple surfaces of the broken bridge (Figure 2). 5(a).

New York: Foster Publishing, 2010.

Jacobs argued from the outset that Minnesota's statute of repose for improvements to real property gave it immunity from suit or liability to any of the parties. Henry Petroski, a structural engineering professor at Duke University, says probably not. 15, 2006. distorted. repairs.

The bridge, designed and constructed in the 1960s, was a steel truss "fracture critical" bridge owned and operated by the State of Minnesota's Department of Transportation. inspected annually instead of every other year.
