Flexural performance of reinforced concrete beams made ...

Feb 01, 2018  Flexural performance was evaluated with a four-point bending test using simply-supported reinforced concrete beams. This kind of flexural test generates a constant bending moment at the beam’s midspan, where maximum strains, moments and deflections occur, and hence, this study was especially focused on load-deformation analysis at the beam ...
