Abstract

In the pursuit of sustainable and recyclable alternatives in construction, Fiber-Reinforced Polymer (FRP) rebars present a compelling option to traditional steel reinforcement. This study aims to analyze and evaluate the tensile strength of FRP rebars compared to steel rebars, with a specific focus on their application in beam reinforcement. The material properties of FRP rebars, specifically ultimate strength, is examined to assess their performance, particularly the brittle versus ductile nature of the materials. To achieve this, five beams, each measuring one meter in length, were cast. While all beams utilized two conventional steel rebars as top reinforcement, three beams employed GFRP rebars at the bottom, one served as a control with traditional steel rebars, and one incorporated BFRP rebars at the bottom. Testing is scheduled for the next semester following curing, and the results will provide critical insights into the efficiency and reliability of FRP rebars as a sustainable alternative to steel. This research acknowledges limitations such as the availability of rebars for further testing and the need for additional tension testing to evaluate other parameters. Despite these constraints, the findings are expected to contribute valuable data to the discussion on advancing sustainable materials in construction, making it relevant to professors and professionals in the field.
