“Adziogol Lighthouse, is one of two vertical lattice hyperboloid structure of steel bars, serving as an active lighthouses in Dnieper Estuary, Ukraine. At 64m it is the sixteenth tallest “traditional lighthouse” in the world.“The lighthouse was designed in 1910 and built in 1911. The 1-story keeper’s house is built within the base.
“Hyperboloid structures are architectural structures designed with hyperbolic 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 effect as well as structural economy.
“Hyperbolic structures have a negative Gaussian curvature, meaning they curve inward rather than outward or being straight. As doubly ruled surfaces, they can be made with a lattice of straight beams, hence are easier to build and, all else equal, stronger than curved surfaces that do not have a ruling and must instead be built with curved beams.
“Hyperboloid structures are superior in stability towards outside forces than “straight” buildings, but have shapes often creating large amounts of unusable volume (low space efficiency) and therefore are more commonly used in purpose-driven structures, such as water towers (to support a large mass), cooling towers, and aesthetic features.”
