Background: Fibers in concrete resist the growth of cracks and enhance the postcrackingbehavior of structures. The addition of fibers into a conventional reinforced concrete canimprove the structural and functional performance of safety-related concrete structures innuclear power plants.
Methods: The influence of fibers on the ultimate internal pressure capacity of a prestressedconcrete containment vessel (PCCV) was investigated through a comparison of the ultimatepressure capacities between conventional and fiber-reinforced PCCVs. Steel andpolyamide fibers were used. The tension behaviors of conventional concrete and fiberreinforcedconcrete specimens were investigated through uniaxial tension tests andtheir tension-stiffening models were obtained.
Results: For a PCCV reinforced with 1% volume hooked-end steel fiber, the ultimate pressurecapacity increased by approximately 12% in comparison with that for a conventionalPCCV. For a PCCV reinforced with 1.5% volume polyamide fiber, an increase of approximately3% was estimated for the ultimate pressure capacity.
Conclusion: The ultimate pressure capacity can be greatly improved by introducing steel andpolyamide fibers in a conventional reinforced concrete. Steel fibers are more effective atenhancing the containment performance of a PCCV than polyamide fibers. The fiber reinforcementwasshown to bemore effective at a high pressure loading and a lowprestress level.
