Aurora Events Center

Grand Forks, ND

The Aurora Events Center houses a recreational arena for football and other athletic events. The curved, steel-framed roof was constructed of long-span steel joists spanning between box trusses. Minutes after erection, the joists on the south half of the roof fell. The joist manufacturer hired SGH to determine the cause of the collapse. Work included review of the joist erection procedures, contractor's daily reports, and construction photographs. SGH made three-dimensional computer analyses of the roof structure. We also conducted laboratory tests of the structural steel used for failed members and suspect connections.
