Abstract

Self-compacting concrete (SCC) has been accepted as a quality product and is widely used. A large number
of studies are available with respect to several parameters, namely, flexural strength, load-deflection behavior,
toughness, ductility, crack control, effects of beam dimensions, concrete filling sequence, flexural toughness
parameters, etc., of fiber reinforced concrete. A suitable method is needed for estimating the ultimate flexural
strength of steel fiber reinforced SCC (SFRSCC) beams. An experimental program was designed, and the test
data have been used for the analytical study. Available analytical methods have been used, and their predictions
are reported. An analytical method is also proposed to determine the ultimate moment of resistance of SFRSCC
beams. A sectional analysis has been developed based on force and moment equilibrium equations. An iterative
procedure involving updating of strain is employed. The predicted ultimate moment of resistance has been
compared with the test data of 48 fiber reinforced SCC beams.
