The Nascar Hall of Fame was designed to enclose a vast 3 dimensional curved track known as the “Flying Ramp” to simulate a race way to display retired racing vehicles. RSD designed the track to be supported on a spiraling central spinal tube to which were attached radiating cantilevered beams to support the sloped deck. The structure was designed to meet automobile gravity and seismic loads for seismic use group II and seismic design category B. Due to irregularity in available support locations the tube supports were extremely varied and required exacting geometric interaction with the architectural drawings. Additionally, the roof structure was designed with a complex rigging system to raise and lower the vehicles on and off the track.
