Expert assessment of the reconstructed reinforced concrete building of the Tagmet JSC workshop

Introduction. It is the first analysis and presentation of the materials on surveys conducted in the pipe rolling workshops of the Tagmet JSC since 1995. The investigations were carried out after the collapse of four roof spans with a total area of 14 thousand square meters. Research Institute of Building Constructions named after V.A. Koucherenko was actively involved in clarifying the causes and eliminating the consequences of the accident for one year. After that the institute's specialists for a long time conducted inspections of the plant's workshop structures in order to issue conclusions on their industrial safety and recommendations for repairing and strengthening worn and damaged elements of building structures for their further safe operation. One of the objects to be surveyed in 2008 was the so-called "Crystal section", which was part of the buildings of pipe welding workshop No. 3 of the Tagmet JSC. Aim. To show one of the ways to possible strengthening of the structures of industrial buildings on the base of the results of a survey of mixed structures, calculations and analyses of their load-bearing capacity reserves. Materials and methods. Visual and instrumental inspections of the technical condition of building structures, analysis of drawings, photographs, plans, etc. Results. As a result of visual and instrumental surveys of the technical condition of building structures of buildings of the "Crystal section" TSC-3 during the inspections and examination of industrial safety of structures of buildings of the Tagmet JSC plant, defects and damages exceeding the values established by current regulatory documents and affecting the operational suitability of the building were revealed. Conclusions. Scientific and technical support for strengthening of the structures of the workshops of the Tagmet JSC, the recommendations of specialists made further safe operation and continuous increase in the commodity productivity of the plant possible.
