In a commpanion paper, a rational mechanical model to predict the entire behavior of point-loaded RC slender beams (a/d＞2.5) without shear reinforcement was developed. This paper presents the test results of 9 slender shear beama and compares them with analytical results performed by the proposed model. They are grouped by two paraneters, which are shear span ratio and concrete strength. There kinds of concrete strength the 26.5, 39.2, and 58.8 ㎫ were included as a major experimental paraneter together with different shear span ratios ranging from 3 to 6 depending on the test series. Tests were set up as a traditional 3 point bending test. Various measurements were taken to monitor abrupt shear failure. Test results were not only compared with analytical results from the proposed model, but also other formulas, to consider the various aspects of shear failure such as kinematical conditions or shear capacity. Finally, a review of the proposed model is presented with respect to the shear transfer mechanisms and the effect of test paraneters. Results show that several assumptions and proposals adopted in the proposed model are rational and reasonable.
