Abstract
The present study goal is to investigate the possible use of Glass Fiber Reinforced
Polymer (GFRP) as an alternative to conventional Steel reinforcement in the
construction sector through a comparative analysis. It offers important insights for
decision-makers and building experts by concentrating on assessing structural
performance, economic feasibility, and environmental sustainability. In the
comparison analysis, Orion simulations with both steel and Glass Fiber Reinforced
Polymer (GFRP) reinforcement for column and beam structures are used. The results
emphasize the materials' notable distinctions from one another as well as their unique
characteristics and implications for structural performance. According to the study,
4Y16 Glass Fiber Reinforced Polymer (GFRP) reinforcement offers improved tensile
strength and corrosion resistance, making it a competitive substitute for 4Y12 Steel,
which is the standard strength for column structures. The recommended usage of 3Y10
Glass Fiber Reinforced Polymer (GFRP) in beam structures rather than 3Y12 Steel
emphasizes how crucial it is to balance weight reduction without sacrificing the ability
to support loads. The research does, however, admit several of the models'
shortcomings, including the assumptions of constant loading conditions and the
omission of elements like cost and ongoing maintenance. The economic analysis,
which is based on information taken from the summary sheet of the Orion software,
demonstrates the significant cost differences between the reinforcement made of Steel
and Glass Fiber Reinforced Polymer (GFRP). The significant cost difference between
Glass Fiber Reinforced Polymer (GFRP) and typical Steel reinforcement makes Glass
Fiber Reinforced Polymer (GFRP) a more financially attractive option, which could
lead to significant construction cost savings.
