Bionic architecture is a part of architecture that uses the forms and organization of biological objects based on mathematical modeling methods and using digital technologies. It is high technology and computer systems that allow modern architects to design skyscrapers, each of which has its own unique style. Such unique structures harmoniously fit into the urban and environmental environment. Bionic and fractal methods allow us to find architectural elements that are interesting in shape and structure. Fractality allows you to create unique forms of high-rise structures that are durable and stable under the influence of external load. The properties of fractality include shear, torsion, sliding, and motion trace. The article discusses the stages of the creation of skyscrapers, the history of their construction in the world. It is shown how bionic shapes help to find the optimal design solution, creating a unique project of a high-rise structure. The achievements of fractal geometry make it possible to create mathematical models of the structure of the artificial environment that a person creates through architecture. It was the development of bionic and fractal architecture that made it possible to create a unique style in architecture. It is necessary to widely introduce mathematical modeling methods into practice to create conditions for more efficient design of modern urban space. Modeling the design processes and the search for optimal solutions using the principles of fractal geometry allows you to create a comfortable urban environment for harmonious human development.
