Behavior of hollow circular steel columns in compression retrofitted with aramid fibre reinforced polymer composites

Abstract

Steel structure is a magnificent pliable material which, in conjunction with the help of both stability and strength, can accomplish both compressive and tensile strength in a manic directing manner. But steel and concrete structures, as of various structural cataclysms and natural cataclysms, slacken their forte in the age which is a recent tricky of noteworthy partisan and societal applicability. The restructuring of structures from these difficulties and subtle earthquakes has now become a vital construction work, both for concrete and steel structures. The results of past experimental studies have shown that structural promotion using fiber strengthened polymers have a sturdily positive effect. The technology provided by Fibre Reinforced Polymer (FRP) sheet has developed a new trend, given the many disadvantages in conventional methods to retrofit structures. This article is an experimental study on Aramid Fiber Reinforced Polymers (AFRP) and its effect on strengthening of Hollow Circular Steel (HCS) column members. In this experimental study, a total of 15 HCS samples have been troupe and tested, including both control and fortified specimens. The results articulated from the number of experiments show that, after application of AFRP and also improved interment of AFRP fabrics, the carriage capacity of the HCS specimens increased. The results were compared to the test specimens and subsequently the properties of the members were studied with the hunt down of load-deflection curves and axial elastic curve after the experimental assessments.
