Utica Memorial Auditorium Recognized As National Historic Civil Engineering Landmark
On August 30, 2011, the Utica Memorial Auditorium was recognized as a National Historic Civil Engineering Landmark.
The Utica Memorial Auditorium, completed in 1960, is one of the very first cablesuspended, long-span roofs in the world and the first to employ a restrained, two-cable method, which was later referred to as a "double layer bicycle wheel roof system." The two-cable system concept utilizes upper and lower cables of different tensions connected by rigid vertical struts. By connecting cables of differing natural frequencies, the roof system is able to dissipate wind-induced fluttering because two cables oscillating at different harmonics would not vibrate. The design was one of the early achievements of famed structural engineer Lev Zetlin who went to complete several other significant projects including the 1964 World’s Fair "Tent of Tomorrow" with architect Philip Johnson. Lev Zetlin's cable roof design has influenced many other tensile structures including Madison Square Garden, Seoul Olympics Gymnastics Venue, Tropicana Field, and the Georgia Dome.
