Cantilever structure in modern construction

This article discusses innovative ways of using cantilever structures in modern construction. It highlights that the unique design of cantilever structures pushes forward the physical possibilities of architecture and construction, challenges the attractive force and breaks stereotypes. The authors provide an analysis of the best worldwide experience of introducing the cantilever elements in the objects of different functional purposes. Unique engineering solutions with a cantilever span of over 20m are paid special attention to. The paper considers the basic technologies, design systems, materials and testing techniques that make it possible to create “flying” structures. Peculiar features of using the cantilever structures in high-rise buildings and high-technology development of high-rise erection are described. Special attention is paid to the economic, safe and environmentally sound technology for the use of lightweight concrete slabs with void formers reducing the amount of concrete and the mass of slabs without losing strength. As a result, the paper describes the prospects for introducing the cantilever elements in modern construction and their functional use
