Geodesic Domes with Installing Floor Using a Cable Stay System

Abstract

AbstractGeodesic domes refer to spatial structures of cover design. Their application provides architectural expressiveness and rational use of building materials. The use of such shells is inextricably linked with a decrease in the consumption of materials for coating structures, a decrease in the cost and construction time. The question of the possibility of embedding the floor in a geodesic dome is being considered, namely, hanging the floor using a cable system. Such a constructive solution will make it possible to use the internal space of geodesic domes more efficiently, to use not only horizontal, but also vertical functional zoning and to increase the usable area of the building several times. The need for research is due to the lack of bases of calculation methods and the necessary experience. The question of the possibility of installing a ceiling suspended with the help of a cable stay system in geodesic domes and a study of load options were studied: the load is applied to the nodes, the load is applied to the rods. Numerical studies and analysis of the stress-strain state of the models have been carried out. Modeling was carried out using the LIRA software package. The operability of the computational models under study has been confirmed. The nature of the distribution of loads over the rods of the system is revealed. The main problems of the proposed circuits are the appearance of stress concentrators in the areas of load application. Solutions for eliminating stress and strain concentrators in nodes are proposed.KeywordsGeodesic domeSpatial structuresInstalling floorCable stay system
