Twisted skyscrapers and structures are gaining popularity in particular due to their aesthetic design and appearance. Twisted structures are more than just an aesthetic element but are meticulously designed structural and architectural marvels. Structures are subject to opposing environmental factors and loads, in particular wind loads that increase with height. Twisting is a construction and design feature to increase stability and tackle the environment and other forces and factors. Architects and designers are developing and creating unique and out-of-the-world twisted skyscraper designs.
Listed here are ten outstanding twisted structures around the world;
