Abstract:
A series of tests on deep beams was performed to examine the impact of load distribution and shear reinforcement on the behavior of the beams. The specimens were subjected to single or double concentrated loads or uniformly distributed loads. Test results indicate differences in behavior among specimens subjected to different load distributions. The differences were apparent in the cracking patterns, failure modes, ultimate strengths, and strain distributions within the beams. Those differences indicate that distributed loads are a much less severe loading type than concentrated loads. The nominal strengths of the specimens were determined using strut-and-tie modeling provisions of both AASHTO LRFD and ACI 318-05 and then compared with the measured strengths.
