Abstract:On the basis of the exposition on the calculation formula of shear capacity in the code for design of concrete structures （GB50010—2002），the placed condition of the minimum of stirrup reinforcement ratio is discussed．And the placed condition of the minimum of stirrup reinforcement ratio is put forward，which is not V>0.7ftbh0，but V>Vc.
Keywords:bending element； minimum of stirrup reinforcement ratio； placed condition； diagonal tension failure
