ASSEMBLY PROCESS OF UNIQUE BUILDINGS USING LARGE - SPAN SPACE SHELL STRUCTURES

Аннотация

Objective. The article explains the development of improved methods for calculating the stressstrain state of unique buildings with long spans, using shell structures during the assembly and disassembly stages, as well as the development of recommendations for the use of effective construction methods and computational design of large-span buildings. Methods. The practical significance of the article is the development of improved structural solutions for reinforced concrete shells of modern combined assembly methods, the use of which is explained by the reduction of material consumption, labor costs for production, assembly and disassembly, and the weight of metal equipment used for their construction. Results. Also, as a result of the research of the assembly process of spatial shell structures using the method of physical modeling, a new cost-effective structural solution for practice and calculation methods, effective methods of assembly and disassembly of structures have been developed, and practical instructions for ensuring the safety of transportation and assembly of structures have been presented. Conclusion. When using this method in the proposed 96x96 m shell cover installation, compared to the use of collector conductors, labor costs are reduced by 26%, and the weight of installation equipment is reduced by 2.4 times. Compared to the use of the column method, labor costs are reduced by 33%, and the weight of assembly equipment is reduced by 2.25 times.
