A Perfect Storm: Indiana State Fair Stage Canopy Collapse

BEC
January 08, 2021
12:00 pm - 1:30 pm
Location
Virtual Meeting via Webinar

ABSTRACT:

On August 31, 2011, a wind gust from an approaching storm caused the temporary canopy structure over the main stage at the Indiana State Fair to collapse, killing seven people and injuring 58 others. The presenter was retained on behalf of one of the primary participants to investigate the cause of the collapse. The assignment required detailed examination of the wreckage, review of storm weather data, structural analysis of the stage canopy structure, testing of the tie-back components used to provide lateral stability, and review of documents defining policies, authority, procedures, and protocols that were to have been used if evacuation was required. Deficiencies were found in many areas. The presentation will discuss how the combination of these deficiencies resulted in this tragedy and how it could have been avoided.

LEARNING OBJECTIVES:

  • Learn the weather contributions to the collapse.
  • Learn the design error contributions to the collapse.
  • Learn the building code provisions relevant to the collapse.
  • Learn the industry standards relevant to the collapse.
  • Be presented with recommendations to avoid similar future collapses.
