Some results of the technical survey and approaches to strengthening of the monolithic reinforced concrete structures of the sports complex “Climbing Center”

Abstract

The construction of sports facilities using cast-in-place reinforced concrete has recently acquired a steady trend towards its development. This was largely facilitated by the development of the regulatory framework for design, as well as modern construction technologies. At the same time, the practice of implementing monolithic structures shows that there is often a low-quality production of construction works. The main defects and deviations made in reinforced concrete structures are shown on the example of the Climbing Center building under construction.One of the main defects was the recorded damage to the corbels of the main pylons of the structure, on which the large-span trusses rest. The survey showed that the result was an unacceptable technical condition of these elements. In order to bring the structures to the standard level of technical condition, a design for strengthening the support nodes of the trusses was developed and implemented, which is presented in the text of the article.
