摘要：
The influence of fiber distribution on the direct shear and flexural behavior of Fiber-Reinforced Self-Compacting Concrete (FR-SCC) is investigated. This study characterizes FR-SCC reinforced with monofilament polypropylene fiber (P) and kinked multifilament polypropylene/polyethylene fiber (PP) at volumes of 0.6, 0.8, and 1.0%. The loss of workability in the FR-SCC mixtures increased the variation in the distribution of the fibers. The residual flexural strength and direct shear toughness increased linearly with the total number of fibers exposed on fracture cross-sections. In general, the P fiber provided better mechanical performance than the PP fiber due to its anchorage effectiveness, which improved the transfer of stress from the matrix to the fiber.
