Pan American Games 2011

Geiger Engineers provided engineering analyses of PRG’s Halo for the 2011 Pan American Games’ opening ceremonies held at Omnilife Stadium in Guadalajara, Jalisco, Mexico. The Halo comprised a circular truss with an inner catwalk and was suspended in the center of the stadium’s roof opening. Geiger Engineers performed a non-linear analysis of the Halo’s support cables using an in-house, proprietary computer program. This allowed the accurate determination of the tension forces that would be exerted on the Halo when it was flown in the stadium. The non-linear analysis results were applied to a structural computer model of the Halo itself to check its capacity.
