Abstract:

The paper presents the effect of reinforcement parameters on the structural behavior of steel fiber reinforced concrete (SFRC) corbels using the general-purpose ANSYS computer program. The parameters studied herein include the effect of fiber index (If), ratio of the main longitudinal steel reinforcement (ρs), yield strength of the longitudinal steel reinforcement (fy), ratio of the horizontal stirrups (ρh), yield strength of the horizontal stirrups (fyh) and ratio of the vertical stirrups (ρv). It is predicted that increase of If improves shear capacity and strain ductility. Steel fiber delays the premature failure for corbels. Increasing ρs improves the shear capacity but reduces the strain ductility. A slight increase in shear capacity is observed by increasing fy. An enhancement on shear capacity and strain ductility is noticed by increasing ρh. On the other hand, a slight increase in shear capacity and reduction in ductility for corbels is observed by increasing fyh. It found that minimum ρv is required only to improve the shear capacity and strain ductility
