WebApr 15, 2016 · Three different failure modes were detected. Beams without shear reinforcement exhibited typical brittle diagonal tension failure. At the maximum shear force V Exp the critical shear crack extended into the compression chord. Simultaneously, an incipient dowel crack along the longitudinal reinforcement could be observed. WebMay 1, 2001 · There is currently a concern that ACI shear design procedures can be unconservative if applied to thick one-way slabs or large beams containing only minimum stirrups. This research discusses the results of 21 large beams tested to look into these concerns. Based on experimental results, this paper concludes that until the present ACI …

WebNov 1, 2010 · Sixteen deep beam specimens, some made of sand-lightweight concrete (SLWC) and others made of all-lightweight concrete (ALWC), were tested and compared with normal weight concrete (NWC) deep beams. The shear span-to-overall depth ratios investigated were 0.5 and 1.0, and the section overall depth varied between 400 mm…. … 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 … each study
