Tensometric Monitoring of Stress-Strain State of Structures of the Underground Part of Buildings and Structures at Scientific and Technical Support of Construction and Conversion Facilities

In this article, the authors describe a method of studying the stress-strain state of reinforced concrete load-bearing structures (piles and pylons) using embedded load cells. The effective dependences of the load on the indirect reactive characteristics displayed on the display of the weight measuring device, which were obtained during laboratory tests of the witness samples of the structures, are presented. Summary tables of the results of stress monitoring in bearing structures during the construction of the object-representative of the study group at the II stage (after concreting the Foundation slab for piles and overlying slab for pylons). The study of the actual stresses in structures will reduce the material consumption of construction by reducing the safety factors for reliability, recommended by the current regulatory and technical base, taking into account significant reinsurance due to the lack of knowledge of the actual VAT field (stress-strain state of structures). As well as carrying out scientific and technical support for the construction and design of unique objects, including geotechnical monitoring of the stress-strain state of the bearing structures of the underground part of such objects with subsequent Desk research and analysis of the data will allow designers, representatives of the developer and construction control services to assess the difference between the design values of loads and the actual stress-strain state of structures.
