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: 0.2 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: 0.3 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: 0.00004 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: 0.08 SJR: 0.153 SNIP: 0.178 CiteScore™:: 1 H-Index: 12

摘要

Steel structures often need strengthening due to increased life loads, or repair due to corrosion or fatigue cracking. Multiple studies have been performed concerning the structural steel beams, while few have been conducted on columns. The stability of columns is very important in steel structures. It is one of the main factors in buckling instability, resulting in large deformations and failure. No independent article, to the author's knowledge, has studied the effect of carbon fiber- reinforced polymers (CFRP) strengthening on slender square hollow section (SHS) steel columns with different boundary conditions. However, this study explored the use of flexible adhesively bonded CFRP sheets in retrofitting slender SHS steel columns by numerical and analytical investigations. The finite element method (FEM) was used for modeling. ANSYS was employed for the analysis of samples. To determine the critical load of SHS steel columns, 15 samples, strengthened with CFRP, were analyzed under different support conditions. The results showed that the support condition and the CFRP coverage are effective in the critical load of columns.
