- Abstract
A database is presented with shear tests on non-slender beams without stirrups subjected to point loads with shear span to effective depth ratios (a/d) < 2.4. From the 338 collected shear tests, 222 tests remained for the evaluations after several selection criteria were applied. The tests were compared with the left part of the shear valley by Kani and did not confirm the strength increase up to the flexural strength in the range from a/d = 2.4 to approximately 1.0. The test results were compared to the strut-and-tie model according to ACI 318-11. The model overestimated the test results. The reduction factor for the strength of the unreinforced struts should be reduced to βs = 0.42 instead of 0.60 for a strut without reinforcement, such as the inclined strut transferring the load to the support for a point load near an end support.
