The goal of this study was to investigate the compressive and flexural behaviors of amorphous metallic fiber reinforced concrete (AM-FRC). Two water-to-cementitious material ratios (w/cm of 0.6 and 0.45) and three volume fractions of amorphous metallic fibers (vf of 0.25, 0.5, and 0.75 %) were considered. To predict the pre- and post-cracking flexural behaviors of AM-FRC beams, sectional analyses were performed using two different material models. Test results indicated that a lower w/cm led to higher compressive strength, higher elastic modulus, and higher brittleness. The compressive strain capacity and post-peak ductility were improved by increasing fiber content. Almost linear increases in flexural strength and deflection capacity were obtained with increased fiber content, while a higher compressive strength (a lower w/cm) resulted in a higher flexural strength but did not significantly change the deflection capacity. The sectional analysis based on RILEM TC 162-TDF significantly overestimated the post-peak ductility of AM-FRC beams, whereas the sectional analysis incorporating the material models proposed by the authors exhibited good agreement with the test data.
