This paper is an experimental study on shear capacity of the high strength R/C beams with a shear span- depth ratio between 1.5 and 2.5. A total of 15 beams was tested to determine diagonal cracking and ultimate shear strength. The major variables are shear span-depth ratio(arid=1.5, 2.0, 2.5), vertical shear reinforcements ratio(Vs = 0, 25, 50, 75, 100%(Vs = PV/PV(ACI)), and concrete compressive strength (f'c =534kg/cm2). Test results indicate that ACI 318-89 Eq.(11-30) overestimates reserved strength carried by arch action and aggregate interlock in shear span-depth ratio 1.5, ACI 318-89 Eq.(11-31) underestimates shear strength carried by vertical shear reinforcements.
