The Toronto SkyDome is a first of its kind sports stadium with a retractable roof which results in, essentially, a fully open air stadium with the roof fully retracted. This unique roof, with its two modes of motion and two different roof structural configurations, and with its nesting principles in the open position, has been designed and erected using conventional structural steel truss technology. The use of standard structural steel hollow tubes has resulted in a roof which has large strength and stiffness characteristics and yet maintained a relatively light weight.
