Abstract

Purpose. Establishing the influence of presence of a longitudinal area, on which there is detachment of layers over a limited length of a composite orthotropic rope, on its stress-strain state. Research methodology. Development of a method for calculating the influence of presence of a longitudinal area, on which there is detachment of layers over a limited length of a composite orthotropic rope, on its stress-strain state by constructing and analytically solving a model of a stress-strain state of a composite tractive element, considering the conditions of interaction of a rope with a permanent structure using the methods of mechanics of layered composite materials with soft and hard layers. Findings. Analytical dependencies are obtained in a closed form, which allow determining a stress-strain state of a composite multi-layer rope with partial local detachment of a separate layer, considering the breakage of one reinforcing element. An algorithm for determining a stress-strain state of a composite multi-layer rope with partial detachment of a separate layer considering the breakage of one reinforcing element is established. Characteristics of a dependency of unevenness coefficients of load distribution in reinforcing elements, displacements and shear angle tangents on the ordinal number of a damaged cable in a presence of partial local detachment of a separate layer of a composite stay rope is established. Scientific novelty. Influence character of presence of a longitudinal area, on which there is detachment of layers over a limited length of a composite orthotropic rope, on its stress-strain state is established. A method of calculating the influence of presence of an area of detached layers in a rope on its stress-strain state is developed. Practical significance. Local detachment of layers is possible in a process of producing a composite multi-layer stay rope. The developed algorithm makes it possible to determine a stress-strain state of composite stay rope with local layer detachment. The known values of detachment allow implementing justified engineering solutions regarding the conditions of safe, temporary use of a composite rope in cable-stayed structure.
