Abstract:
Although considerable research has been devoted to the effects of stirrups as shear reinforcement, bent-up bars which have been used for many years and are included in the reccomendation of all codes of practice, have received little systematic study. This paper presents a direct comparision of three forms of web reinforcement, vertical and inclined stirrups, and bent-up bars, and it is found that the web reinforcement ratio provides a satisfactory basis for the evaluation of the relative efficancy of these types.
