The Twist
The form, volume and structure of the towers is generated by two ellipses, one at foundation level and the other at a horizontal plane at 450 m (1,480 ft). These two ellipses are rotated relative to another. The tightening caused by the rotation between the two ellipses forms a "waist" and a densification of material halfway up the tower. This means that the lattice structure, which at the bottom of the tower is porous and spacious, becomes denser at waist level. The waist itself becomes tight, like a twisted rope; transparency is reduced and views to the outside are limited. Further up the tower the lattice opens again, accentuated here by the tapering of the structural column-tubes.
The Canton tower's twisted shape or hyperboloid structure corresponds to the Russian Empire patent No. 1896, dated 12 March 1899 received by Vladimir Shukhov, the Russian engineer and architect. The structure is similar to the Adziogol Lighthouse (designed by Vladimir Shukhov in 1910) in Ukraine's Dnepr delta.

Famous quotes containing the word twist:
“The duce of any other rule have I to govern myself by in this affair—and if I had one ... I would twist it and tear it to pieces, and throw it into the fire when I had done—Am I warm? I am, and the cause demands it—a pretty story! is a man to follow rules—or rules to follow him?”
—Laurence Sterne (1713–1768)
“I believe in the total depravity of inanimate things ... the elusiveness of soap, the knottiness of strings, the transitory nature of buttons, the inclination of suspenders to twist and of hooks to forsake their lawful eyes, and cleave only unto the hairs of their hapless owner’s head.”
—Katharine Walker (1840–1916)
