008 Longitudinal Reinforcement Design Beams Part2

For a given rectangular concrete beam, according to Eurocode 1992-1-1:

1. Determine the procedure for calculating the resistance bending moment A concrete rectangular cross-section, 300×500, is made of C30/37 and reinforced by B500 steel. Assume the stirrup is T10 and the required nominal cover is 35mm:
2. With 4T20, determine the bending moment resistance.
3. With 4T25, determine the bending moment resistance.
4. With 4T32, determine the bending moment resistance.
5. Compare the steel percentage increase results and the corresponding bending moment increase.

PS. Neglect the effect of compressive steel.

Dimensions are in mm. A positive bending moment is assumed to be applied.
