CONSTRUCTIONS SYNTHESIS OF PIVOTAL SYSTEMS

Abstract

The characteristic features of the supporting structure are its topology, geometry and parameters of the elements. The process of creating a structure goes from the project to its material embodiment. The topology defines the contour of the load resistance, which finally manifests itself in the configuration and material. The fundamental beginning of the design project is the variational principle of structural synthesis with energy content. It provides a minimum consumption of material. Its fundamental distribution is made at the stage of topology design as a confrontation with an external force field. Geometry is more subordinated to directive settings related to the nature of the load and the functional purposes of the structure. The parameters of the elements complete the definition of the configuration, ensuring satisfaction of the conditions of strength, rigidity and stability of equilibrium. The scientific results concerning the consideration of the influence of configuration on the operational qualities of the structure and the approach to the practical theory of structural synthesis are used. A four-rod system is chosen to illustrate the design methodology. The regulation of strength and stiffness parameters can be effectively carried out when using composite materials, in particular, fiber-reinforced concrete, since the change in strength is correlated with the parameters of the fibers and their percentage with a slight change in the modules of the material.
