Comparisonof steel stirrup and GFRP stirrup with specific reference to structural feasibility, self-weight,and costusing ‘Ansys’ software.

Abstract

To get in collaboration with modern infrastructure; various research studies indicate for sustainable replacement of steel rebar with glass fibrereinforced polymer (GFRP) rebars. In standard column, share of steel is up to 8%. The steel reinforced structures create problems such ashandling of steel, transportation, self-weight of steel, and importantly its costwhereasGFRP rebar has properties like high strength, corrosion resistance, durability, and light weight & cost effective in nature. This researchpaper enhances replacing the steel stirrups in Column with GFRP stirrups,investigatesthe feasibility through structural behaviourusing ANSYSSoftware, checksreduction of self-weight & Cost and is ultimately targeted to light weight structures orfloating offshore structures.To check the feasibility ofreplacement, reduction of self-weight and cost, this research is divided into three stages. In first and second stage, it shows selection of GFRP as replacement material and structural feasibility. In further stage, it shows comparison between square, rectangular and circular column having conventional reinforcement, Semi GFRP and full GFRPreinforcement, to check effective self-weight and cost reduction.When Conventional Column compared with Semi GFRP and full GFRP reinforced column, effective reduction showed in full GFRP column and self-weight reduced up to 6 % and cost decreasedby 42%. The effective reduction percentage was noticed in rectangular column as comparedto other shapes where slightly less reduction is observed
