This research explores the feasibility of using Basalt Fiber Reinforced Polymer (BFRP) wire as an alternative to conventional steel wire for prestressing in Prestressed Concrete Cylinder Pipes (PCCP). Given the increasing need for durable and sustainable construction materials, BFRP offers advantages such as high tensile strength, corrosion resistance, and reduced weight. The primary objective of this study is to assess whether BFRP wire can achieve a prestress force as achieved with steel wire, which is essential for maintaining the structural integrity of PCCP. The methodology involves several critical steps, beginning with the establishment of the required prestressing force and referencing the tensile strength of BFRP from existing literature. The necessary cross-sectional area of the BFRP wire is calculated to withstand the specified prestress using established equations, followed by determining the diameter of the wire based on its circular cross-section. To effectively distribute the prestressing force, the analysis incorporates two layers of BFRP wire, allowing for the force to be divided between them. The study concludes by determining the number of wires needed in each layer to meet structural requirements, considering the effective area necessary for achieving the desired prestress. The findings indicate that a specific diameter of BFRP wire is required for the two-layer system to sustain the targeted prestress force. This novel research suggests that BFRP wire is a viable alternative to steel wire in PCCP applications, potentially enhancing durability and longevity, with future work focusing on experimental validation and long-term performance assessments under varying environmental conditions.
