Abstract

Abstract Scaffolding structures are commonly statically indeterminate and therefore the load-bearing capacity of the elements is not fully used, and the load-bearing capacity of the structure is limited by the most loaded element. It is important to redistribute the forces in the structure elements to make the most efficient use of their load-bearing capacity. It is suggested to introduce force limiters into the most loaded elements that allow shifts inside the element when the force limit value is reached. Due to this displacement the forces inside the element are reduced and redistributed to the adjacent elements. A numerical analysis has been carried out on the example of wall construction to assess the impact of the force limiter on the load-bearing capacity of the structure. The article presents the design of a force limiter designed for vertical diagonal. Laboratory test of the force limiter as part of scaffolding assembly was carried out.
