Concrete Beam Testing

The principle of the test is to determine the flexural strength of hardened concrete specimensDestructive test of a beam of rectangular section of reinforced concrete subjected to the simp
le bending. The bending moment acting in the beam is worth
M = F.L / 2
with F = applied force; L = Scope of the beam.

Beam resists with section steel frames
A = M / (d.fe) with M = bending moment, d = distance from the upper fiber of the beam to the center of gravity of the tensioned steels; fe = elastic limit of steel
Here is a video of a test project
