Work of Combined Connections When Reconstructing the Grand Sports Arena of "Luzhniki" Stadium
When preparing the Grand Sports Arena of «Luzhniki» Stadium for the 2018 FIFA World Cup, it was necessary, according to FIFA requirements, to increase the number of seats in the stands. One of the most laborious works was the implementation of a new design of the visor which increases the existing covering. The upper belts of the console part of the visor should be attached, using various methods, to the nodes which lean via the elements of the internal contour on the structures of radial beams. The connection of all elements of the existing covering was performed with high-strength bolts. The article investigates the bearing capacity of high-strength bolts with the use of full-scale specimens of connecting nodes of the new design of the visor with the existing structure of the internal contour of the covering. When reconstructing the covering, there was a need for welding. Tests with real samples were conducted with the purpose to substantiate the possibility to use the combined connections when reconstructing the unique object.
