Abstract
This research presents the test results of experimental study on shear strength of reinforced
concrete flanged beams. The test variables in this study were flange dimensions (thickness)
and the reinforcement in flange. seven simply supported specimens, consisting of one of them
with rectangular cross section and the remaining specimens with T section, subjected to two-
point loads were tested until failure. During the test, the values of the diagonal cracks, crack
width, strain and the maximum load were observed as well as the deformation of the beams. It
was confirmed from the test that the shear capacity of T-beam was higher than for rectangular
beams, with the values ranging from 166 to 312%, depending on the flange dimensions and
longitudinal reinforcement in flange. In addition, based on the test results, a simple model for
predicting the contribution of flange to shear capacity in T-beam was presented and
comparison the results.
