Twisted Buildings And Structures
Buildings can appear to be twisted by design, where the twisting (Torsion (mechanics), torsion, helix, etc.) is structural rather than merely an ornamental detail. The Council on Tall Buildings and Urban Habitat defines a twisting building as one that progressively rotates its floor plates or its façade as it gains height. There are 41 spiraled skyscrapers, and 4 more are under construction. Turning Torso, in Malmö, Sweden is regarded as the first twisted tower or building. It was designed by Santiago Calatrava and was completed in 2005. When completed, Diamond Tower (Jeddah), Diamond Tower will be the only building to twist a full 360 degrees along its height. F&F Tower, in Panama City, holds the record for the tightest twist, that is, the highest average rotation per floor, at 5.943 degrees across each of its 53 floors; and as of 2017, it is the completed building with the highest total rotation, with 315 degrees.

Torsion (mechanics)
In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion could be defined as strain or angular deformation, and is measured by the angle a chosen section is rotated from its equilibrium position. The resulting stress (torsional shear stress) is expressed in either the Pascal (unit), pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf). In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius. In non-circular cross-sections, twisting is accompanied by a distortion called warping, in which transverse sections do not remain plane. For shafts of uniform cross-section unrestrained against warping, the torsion-related physical properties are expressed as: : T = \frac \tau= \frac G \varphi where: * ''T'' is the applied torque or moment of torsion in Nm. * \tau (t ...
