This induces a symmetrical triangular stress distribution along vertical sections (assuming elasticity) from compression above the neutral axis at midheight to tension below the neutral axis. The flexural strength (the maximum tensile stress at the bottom surface) is FL/bd2 where F is the total load, L is the distance between Strength-testing machines for concrete the lower supporting rollers and b and d are the breadth and depth of the beam. The Standard gives details of the testing rig and requires that the compression testing machine used to apply load shall conform to BS EN 12390-4.
