383 pages : ill. ; photo.; col. ; 28 cm. This monograph presents the results of theoretical and experimental studies, as well as the design and construction-features of structural systems with rational parameters. It starts by outlining issues around the topological (bionic) optimisation of structures and suggests ways to address them. The computational compiler underlying the proposed approach incorporates the finite element method and the adaptive evolution method. Thus, this volume outlines new energy principles that speak in favour of the proposed methodology.
