dc.descriptionA deeper understanding in the transverse impact of wire ropes is required to be able to design more and improved structures to reduce the soaring loss of human lifes in traffic accident, by fall of object in mines and the huge amount of rockfalls and landslides ubiquitous all along the rugged geography that we have. By all these reasons, in this thesis are given the mathematical models of the forces in the ends of a steel wire rope and the movement of the body that impact transversely in its middle point. To achieve these objectives, both ends of the wire rope are considered rigidly fixed, reducing its geometry to an unidimensional elastic string and modeling the body as a material point that could be a rock, automobile or any machinery that could fall over a protection barrier, achieving this way a high level of acceleration what in turn induces large displacements and internal stresses around the contact zone in the wire rope. Next the models are validated using the developed equations to calculate the reaction of the steel wire ropes type 3x7 and 1x7, assuming equal conditions imposed in previous investigations done about protection barriers. At the end is concluded that all models, excepting the model of internal stresses, express the physics present in the referred experiments and simulations thus contributing to augment our knowledge about the transversal impact of steel wire ropes. And additionally, it has been contributed with a method to determine the frontier conditions in a transversely impacted string that can also be used as basis to solve more general problems, as the oblique impact of wire ropes.es_PE
