Diagonal tension in t-bemas without stirrups

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 …
