ABSTRACT

This research article has been analyzed to examine the structural enhancement of concrete-filled steel tube (CFST) sections used externally with carbon fiber reinforced polymer. Due to their structural benefits, concrete-filled steel tubular sections are among the most common today. High strength, reduced cross-section, excellent seismic-resistant structural properties, increased fire resistance, and improved visible stiffness are just some of the advantages. Carbon fiber was used as a form of strips with a different number of layers and strip spacing on beam and column specimens. Twelve columns were tested, ten of which were externally reinforced with CFRP strips of various widths and spacing, and the remaining two columns were not reinforced with carbon fiber. However, ten beams were tested, eight of which were externally reinforced with CFRP strips of various widths and spacing, and the other two beams were not reinforced with carbon fiber. All specimens were tested at one point loading under a universal testing machine. Experimental results found that in comparison to the reference column and beam, the CFST column and beam specimens reinforced by carbon fiber have a higher load capacity.
