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

ABSTRAKT

Mechanical vibration dampers (MVD) can be used for reduction of vibrations of tower type structures. A method of determination of optimum parameters of MVD mating with this type of structures is briefly described in the paper. The elaborated computational method became the basis for design solutions. During the last years in Poland, MVD have been applied to reduce vibrations of transmitting antennas installed on the tops of several guyed masts and steel towers. Observations by users of the objects, on which the first group of mechanical vibration dampers had been installed, was presented and analyzed in [1]. Remarks and conclusions placed in the questionnaires of the users of the objects fully confirmed efficiency of these dampers at a considerable range of building's vibration reduction. Since the publication [1] a number of new dampers cooperating with tower structures (masts, steel chimneys) were designed and constructed. New observation results of behavior of the structures with dampers during exploitation have also been collected. All this has been used in this paper for presentation of generalizing conclusions useful mainly for designers of tower type - structures that must be protected against vibrations.
