This paper on deep beams with inclined web reinforcement gives supplimentary information to that in a previous ACI paper on web reinforcement effects on deep beams. Tests were carried out on 10 simply supported deep beams incorporating different amounts of inclined web reinforcement. The range of span-depth ratios L/D studied was from 1 to 3, and the range of clear shear span-depth ratios x/D from 0.23 to 0.7. Ite was found that inclined web reinforcement was consistantly highly effective for crack and deflection control and for increasing ultimate shear strength, for all the L/D and x/D ratios investigated.
