The Shukhov Radio Tower (Russian: Шуховская башня), also known as the Shabolovka Tower (Шаболовская башня), is a broadcasting tower deriving from the Russian avant-garde in Moscow designed by Vladimir Shukhov. The 160-metre-high (520 ft) free-standing steel diagrid structure was built between 1920 and 1922, during the Russian Civil War.
The Shukhov tower is a hyperboloid structure (hyperbolic steel gridshell) consisting of a series of hyperboloid sections stacked on one another to approximate an overall conical shape. The tower has a diagrid structure, and its steel shell experiences minimum wind load (a significant design factor for high-rising buildings). The tower sections are single-cavity hyperboloids of rotation made of straight beams, the ends of which rest against circular foundations.
