Perilaku Struktur Balok Beton Bertulang Dengan Penambahan Serat Polipropilena

Abstract

This study investigates the effect of polypropylene (PP) fiber addition on the flexural strength, crack resistance, and plastic deformation of reinforced concrete beams. The fiber contents tested were 0%, 0.5%, 1%, and 1.5%. The results show that adding PP fibers significantly improves the flexural strength and crack resistance, with the greatest improvement observed at 1.5% fiber content. Plastic deformation also increased in beams with fibers, particularly at 1% and 1.5%. Numerical simulations supported the experimental findings, showing a more uniform stress distribution in beams with fibers. The study concludes that polypropylene fibers effectively enhance the performance of reinforced concrete, making it more durable and efficient for construction applications.
