The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

The rain-wind induced vibration of stays is a phenomenon discovered recently and not well explained yet. As it is influenced by a wide range of physical parameters - wind speed, direction and turbulence, material water repellency, surface roughness, waterfall quantity, rain drop size and speed, cable size and shape, cable weight, pre-strain and also mechanical damping - this peculiar phenomenon is difficult to be reproduced in laboratory controlled condition. From a successful wind tunnel experimentation, in which physical data was measured, an extensive analysis was performed to identify the parameters of the rain-wind induced excitation. The unsteady pressure field and water thickness around the cable model were measured under rainy-excited conditions. The knowledge of those parameters provided helpful information about the air-flow around the cable and allowed to clarify the physical phenomenon which produces the excitation. Following this process a mechanical model of the exciting mechanism was elaborated and its parameters were calibrated by fitting the experimental results. The aim of this model is to help with comprehension of the phenomenon. In future it can be used to calculate the sensitivity of a cable structure to this dramatic excitation and also to assess the right level of countermeasure, necessary to avoid it.
