In this study we summarized the experimental results of (166) beams in (22) researches about the shear behavior of a self-compacting concrete beams without stirrups. We calculated the nominal shear strength of these beams according to the equations of the normal concrete in six global codes (ACI‑318‑14)، (AAS3600-2009)، (JSCE-2006)، (NZS3101-2006، )EC2-2004)، (BS8110-1997), Then we conducted a statistical study of (performance factor) the ratio of experimental shear force to shear force calculated according to these codes, it was clear that the calculation according to <strong>(</strong><strong>AAS3600-2009</strong><strong>)</strong> gave the lowest coefficient of variation (COV=28.46%), While (pf=1.81%), and the coefficient of determination (R = 0.76) did not meet the requirement of (R <0.8), while the calculations according to the British code <strong>(BS8110-1997)</strong> gave the largest correlation factor between the studied codes (R = 0.86), but (COV=33.69%), and  (pf=23.49%).</p> <p>We also conducted a statistical study of the results of the calculation of the beams according to the relations proposed in (8) reference studies where the relationship proposed by <strong>Bazant and Sun1987</strong> gave the lowest coefficient of variation (COV = 27.03%) and coefficient of determination (R = 0.89), but (pf=68.67%), while the equation proposed by <strong>Frosh 2003</strong> gave (COV = 45.33%), (R = 0.71), (pf=1.81%), which is a good ratio</p>}, number={4}, journal={Tishreen University Journal -Engineering Sciences Series,}, author={جحجاح غاندي and الخطيب وعد}, year={2020}, month={Oct.} }
