WebMar 22, 2006 · The diagonal-tension (shear) mode of failure is noticed in the RC specimen for the a/d ratio of 3.0, whereas the flexural mode of failure is noticed for the SFRC specimen with 1 % steel fibers for ... Web2. The presence of these bars restricts the growth of diagonal cracks and reduces their penetration into the compression zone. 3. The stirrups also counteract the widening of cracks. 4. The stirrups are arranged so that they tie the longitudinal reinforcement into the main bulk of the concrete. BEAMS WITH VERTICAL STIRRUPS
WebApr 16, 2024 · During the testing, the RC beam (R160) provided with conventional stirrups at 160 mm spacing as transverse reinforcement has failed by developing a diagonal tension crack in shear span as expected (Fig. 8a). This is because the beam R160 was intentionally designed to fail in shear by keeping the spacing of stirrups (160 mm) larger … WebA theory is presented to predict the ultimate shear strength of T-beams of long shear span without web reinforcement. Failure is assumed to occur in the compression zone above …
