COLLAPSE! An Engineering Response to the Unthinkable Modern-Day Structural Failure

In December 2010, Minneapolis was inundated with over 17 inches of snow fall in an historic snow storm. The build-up of snow, ice, and water proved to be too much for the inflatable fabric roof structure of the Hubert H. Humphrey Metrodome as it ruptured dramatically, spilling snow and ice onto the empty field. This event created unique damages to a unique structure, requiring an equally unique solution that could mitigate further damages to the structure, reduce risks to its occupants/workers, and expedite the structure’s return to service. The presentation will highlight the structural engineering emergency response activities, ranging from structural.
