Requirements for the Monitoring System of Wire Rope Cable Breaks

Abstract

One of the modern trends in the improvement of structures in construction is the use of steel-reinforced concrete systems. In such systems, cable-stayed ropes are used to absorb tensile forces. The cited works did not consider the issue of the interaction of the rope and the node connecting its ends to the structure. Ropes are used in various fields of technology: suspended cableways, mine and elevator equipment, lifting cranes, etc.
 The construction of such ropes is close to traditional round ones. At the same time, the conditions of operation, assembly of structures using them are different from traditional round ropes. Thus, cable-stayed cables of bridges perceive significant wind loads. Transportation of ropes for the perception of significant loads is complicated due to their significant bending stiffness.
 An elliptical shape or a shape similar to this section of the rope will reduce the impact of wind loads. Technically, this can be implemented by creating a cable rope as a composite structure in the form of a system of parallel cables connected by an elastic material, such as polyurethane or rubber.
 A multi-layer rope can be obtained by vulcanizing the connection of single-layer or double-layer rubber ropes directly at the installation site. The practice of use has proven their advantages - the service life of rubber balancing ropes exceeds the service life of ordinary ropes by 6 times.
 The design requirements of the study will contribute to those given in the bridge design standards and will correct the current lack of knowledge regarding the analysis of sudden or gradual cable pull. This will also provide a more realistic estimate of the dynamic amplification factor expected in the case of failure. The requirements for the gust detection system are intended to provide a potential improvement in the structural strength of cable-stayed bridges and provide economic benefits to society.
