Dept., College of Engineering, University of Mosul, Mosul 41002, Iraq *Corresponding Author: [email protected] Abstract This study investigates the shear behaviour of Self Compacted Reinforced Concrete Beams (SCRCBs) with and without stirrups for different concrete strengths using finite element modelling (FEM) by ABAQUS software. The FEM can give a satisfied understanding of local behaviours of structural parts when the simulated model is verified by experimental results. In the current study, the compressive strengths of concrete (25, 35, 45, 60, 75 and 90 MPa) and shear span to depth (av/d) ratios (1, 2.2, 3.3 and 4) are used as parameters. An excellent matching was shown between the simulated model with the FEM and the experimental results. Based on the results, it was found that the mean value of (Vu EXP /Vu FEM ) ratio, the standard deviation (Sd) and the correlation factor (R) are 1.065, 0.106 and 0.980, respectively. Also, the results indicated that the variation of compressive strength and (av/d) ratio have a visible effect on the shear behaviour of concrete. In addition, the shear reinforcement resistance does not have a clear impact on the shear capacity of SCRCBs with the variation of (av/d) ratio and it does not reach the yielding strength at peak load. The developed ACI formula, which is proposed to predict the shear capacity, exhibits an excellent correlation with the experimental and the FEM results, so, it can be recommended to apply it in predicting the shear capacity of both deep and slender reinforced SCC beams.
