Abstract:

The results of a nonlinear analysis model of reinforced concrete beams using a high performance fiber reinforced cement based matrix, particularly SIFCON (Slurry Infiltrated Fiber Concrete) are described and compared to experimental observations. The use of a fiber reinforced matrix in the compression zone of a reinforced concrete beam allows for otherwise over-reinforced sections to achieve significant increases in structural ductility while resisting loads close to their ultimate load. Ductility and energy ratios, normalized by the control beam without fibers, ranged from 2.47 to 3.60 and 3.28 to 5.69 respectively; that is several hundred percents in improvement. The analytical model is shown to predict, with reasonably good agreement, experimental observations of moment-curvature and moment-deflection curves.
