Monitoring the technical state of load-bearing structures of the Luzhniki Stadium during reconstruction

Introduction. The paper presents the methods of reinforcing brick-and-stone structures, as well as monitoring of their strain capacity during the reconstruction of the Grand Sports Arena of Luzhniki Olympic Complex. The authors paid special attention to the methods for ensuring the preservation of front wall made of ceramic hollow stones.

Aim. To ensure the reliability and stability of the wall of the Grand Sports Arena during the stadium reconstruction, in particular during the dismantling of the framework and stands.

Materials and methods. The authors calculated the strain capacity (vertical deviation) of the framework of the stands at its dismantling stage and the wall stability, taking into account the framework fastening with rolled steel braces. The wall section taken for calculation at the first stage of dismantling stands consisted of several spans of 6 meters each. An extreme wind action was considered as the main stress factor that has the most severe impact on the front wall strain.

Results. The calculations showed that the wind load on the system “front wall + 1 span of the stand framework” increases tensile and compressive stresses in the load-bearing elements by no more than 5–7% compared to the system “front wall + 2 spans of the stand framework”. Based on the calculations performed, only one span of the stand framework adjacent to the front wall was decided to retain. Monitoring of the structures strain confirmed the reliability and efficiency of the adopted solutions to strengthen the retained structures.

Conclusion. Due to R&D support for the design and reconstruction of the Luzhniki Grand Sports Arena, complex issues arising in the process of reconstruction were efficiently solved. The principles of the Arena reconstruction can be applied to other similar facilities.
