Wind Engineering for the Las Vegas Stratosphere Tower

A wind tunnel model of the Las Vegas Stratosphere Tower was first tested as part of its design in 1991, but this proved to be only the beginning of a long series of modifications and additions that warranted additional wind-engineering investigations lasting through 2004. These features included proposed changes in geometry, a proposed extended spire that would have made it the world’s tallest free-standing tower, construction challenges that required evaluation of wind loads on partially completed segments for limited exposure periods, the addition of several amusement rides, and the proposed addition of a variety of broadcast antennas. Integration of wind engineering and structural design concepts have allowed the extension of tower operations by the addition of several new attractions without compromising structural integrity.
