In the previous video, the design bending moment for the middle beam has been determined. For the same beam:
The beam is 250mm in width and 500mm in height. Concrete class C30/37, reinforcement of B500 and take the nominal cover of the beam to be 35mm. T16 for the longitudinal and T10 for the stirrup is suggested to be utilized.
