Shukhov tower on the Oka River
Encyclopedia
The Shukhov Tower on the Oka River (also Dzerzhinsk High-Voltage Mast, Shukhov Oka Tower) is the world’s only hyperboloid
Hyperboloid structure
Hyperboloid structures are architectural structures designed with hyperboloid geometry. Often these are tall structures such as towers where the hyperboloid geometry's structural strength is used to support an object high off the ground, but hyperboloid geometry is also often used for decorative...

 crossing the Oka River commissioned between 1927 and 1929. For the Oka River crossing, six hyperbolic pylons (three for each powerline) were built: a 20 metres (65.6 ft) tall anchor pylon, a 68 metres (223.1 ft) tall crossing pylon on the hillier south shore, and a 128 metres (419.9 ft) tall crossing pylon on the lower terrain of the north shore.

In 1989, the power line was rerouted and the 20- and 68- metre pylons were dismantled. The 128 metre pylons were left intact as a monument. Today, only one of the 128-metre pylons stands as the other was illegally demolished to sell its steel in May 2005.

Structure

The Shukhov Tower consists of five 25 metres (82 ft) steel lattice sections, formed by single-cavity hyperboloids of revolution. The pylon sections are made of straight profiles, the ends of which rest against circular foundations. The tower's circular concrete foundation has a diameter of 30 metres (98.4 ft).
