An FHWA research project to assess the performance and design of steel gusset plate connections facilitated actions that addressed one of the final NTSB recommendations.
He covers the design and analysis for smart partially restrained concrete-filled tube connections, both end plate and T-stub types; for bolted connections, including component models for recentering bolted connections; and for gusset plate, recentering slit damper and smart damping smart connections.
Similarly, the I-35W bridge failure in Minneapolis in 2007 was a fracture-critical situation, in which a gusset plate was too thin, owing to a design flaw.
However, the I-35W investigation also found that the "corrosion documented on the gusset plates" had been "overlooked or underestimated by bridge inspectors using visual inspection methods," and the NTSB made safety recommendations asking the FHWA to require more in-depth inspections to detect gusset plate corrosion.
An investigation by the National Transportation Safety Board assisted by the FHWA determined that the immediate culprit was a failed gusset plate, one of the flat, heavy pieces of steel that are bolted in pairs to join the ends of the steel members that form the bridge truss, according to Justin Ocel, an FHWA engineer.
After the collapse, the UK- based company said it feels that the orientation of the gusset plate were in wrong plane.
Writing in Firehouse magazine, John Norman, a captain with the Fire Department of New York, cautions that "buildings which were constructed using plywood I-beams, 2x4 gusset plate trusses, or the composite steel and wood trusses have all been proven to collapse [within] as little as five minutes of fire exposure.
A bent gusset plate was photographed and filed in 2003.
For gusset-plate joints, an increase in length of the gusset plate from 4 to 8 inches increased the moment capacity for both glued and unglued joints, but a further increase of the length did not result in any significant increase in the strength.
