ABSTRACT

During the proposed rope design, expressions to calculate the acceptable values for changes in geometric parameters and mechanical properties of spiral elements and the waviness angle of a steel rope, depending on its torsion, bending, and ultimate strength of the wire material, affecting development of emergency situations, are determined. The obtained expressions allow determining the acceptable value of the waviness radius, allowing further safe use of a rope, as well as parameters of trouble-free operation of a construction. Recommendations made on the basis of the expressions determining the acceptable values of the rope waviness radius will improve safety of construction involving a strand anchor system. The obtained expressions to determine the acceptable values of the waviness radius upon deformation nonlinearity are more efficient than calculations performed using the linear theory of rope design, which will allow for more accurate design of ropes in a strand anchor system, affecting, in its turn, operational reliability of a strand anchor construction. The obtained expressions will also have an impact on prevention of emergency situations involving such constructions.
