In-plane dynamic behavior of cable networks. Part 2: prototype prediction and validation

An analytically based and numerically implemented method for the prediction of the behavior of cable networks has been developed for the analysis of the in-plane free-vibration problem of a set of interconnected taut cable elements. The methodology has been extended to large systems with complex configurations and applied to the study of the oscillation mitigation of a real case on an existing cable-stayed bridge. tion of the model has been performed through the comparison of the predictions with experimental data derived from an extended ambient survey on an actual structural system. In addition, the study includes a sensitivity analysis related to the introduction of design modifications to the original configuration. The observations deduced from this research have contributed to the definition of preliminary criteria for the selection of an optimized system.
