Toroids


Toroids are appearing in structural applications due to their aesthetic & structural benefits. Examples include the Dubai & Osaka airport terminals, and London Museum. However the structural efficiencies of this shape are also being applied by Triodetic in long-span ore stockpile enclosures. Toroid shapes are simply described as a double curved surface that resembles part of a tyre or inner-tube. The toroid shape has curvature in two planes & therefore can be designed as a shell.
	This results in less structure mass than linear designs and by controlling the angle of the structure wall at its base, footing reactions can be minimized. Overall structure curvature & member sizes must be designed to resist buckling & to restrain surface discontinuities, however these structures can be very economical & fast to construct.
