Shear behaviour of R.C. beams with water-stop joints

The paper presents a research on the shear behaviour of R.C. beams with and without water-proof construction joint or bonded construction joint. 24 Beams were tested in an asymmetrical four-point flexure test configuration, considering three different reinforcement ratios. As expected, this parameter strongly affects the results of bending/shear failure. The effects of the type of joint and of the reinforcement ratio are discussed in terms of cracking and ultimate behaviour.
