The purpose of the study is to investigate the validation on the design for resisting the sliding shear of New RC beams specified in NZS 3101-2006, by means of collecting some data of New RC beam testing performed recently. Meanwhile, this study planned two beams, prototype beam N1 for benchmark and the beam N2 with 45-degree bent-up steel reinforcement designed to relocate the plastic hinge away from column face. The length of the testing cantilever beams is 2 m. SD690 #8 for longitudinal reinforcement and bent-up bar, and SD 420 #4 for transverse reinforcement are used. The concrete strength is 60 MPa.
The test results show that beam N1 produces sliding shear cracks at the column face to DR=5%, while N2 suppresses sliding shear cracks due to the additional bent-up bars until the sliding shear cracks relocated at the column face to the later stage of the test DR = 6%. Also, it was found that the design of sliding shear in NZS3101-2006 code is applicable but relatively conservative for the New RC beams.
