SHELLS AND ROD STRUCTURES IN THE FORM OF ANALYTICALLY NON-GIVEN SURFACES IN MODERN ARCHITECTURE

Abstract

N the XXI ^th centurypracticallyinallcountries, erectionsin the form of analytically non-given surfaces areappeared. Architecture of arbitrary shapeswasspringingup. Architectsusedtheirentire arsenal of analytical surfaces suitable for realization of their creative ideas. The investigations carried out in RUDN showed that only 43 analytical surfaces from 600 known surfaces found the application in the World at present time. But many noted and young architects and designers began to use surfaces that are impossible to give by analytical formulas. Their intentions were realized into many civil, public, and industrial erections and they came to be as the architectural sights of the towns and countries equally with the erections built before in the form of canonical surfaces. In a paper, the examples of the most interesting buildings are presented; the classification of shells and shell spatial structures of free forms is given according to their analysis schemes, material, and structural solutions. The aim of presented research is to elucidate an extent of involving of architects, geometricians, and designers into working up and building of shells and rod structures in the form of analytically non-given surfaces.
