Abstract:
Ten 35 x 35 x 2.75 in. (890 x 890 x 70 mm) concrete panels were tested under in-plane pure-shear monotonic loading conditions to evaluate the effectiveness of steel fibers in meeting minimum shear reinforcement requirements for concrete elements. The test results indicate that concrete elements exhibiting ductile behavior, sufficient shear strength, and good crack control characteristics can be obtained with an adequate addition of steel fibers, meeting or exceeding the level of performance achievable using codeprescribed minimum amounts of conventional shear reinforcement. Fiber aspect ratio, fiber length, fiber tensile strength, fiber volume content, and concrete compressive strength are found to influence the shear performance of fiber-reinforced concrete (FRC) to varying extents. Details and results are provided.
