The number of carbon fibre reinforced polymer (CFRP) layer and their orientation generally affect the strength and stiffness of the steel circular hollow section (CHS) members primarily when they are subjected to bending. In this study, numerical investigation is carried out to find the effect of number and orientation of CFRP composites layer on strength and stiffness of CHS members under bending. In numerical investigation, cohesive element is adopted to model interface element (adhesive) and an 8-node quadrilateral in-plane general-purpose continuum shell is used to model CFRP elements. The validity of the FE models is ascertained by comparing the ultimate load, stiffness and failure mode from experimental results. The results of FE analyses show that the strength and stiffness increase with the increase of number of CFRP layer. The three layer configured CFRP strengthened steel CHS beams are found cost effective with respect to strength increment than four layer configured CFRP strengthened steel CHS beams

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
