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. 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…. …
