013 Longitudinal Reinforcement Design T-Section Part3

In a T-Section made of concrete, determine the procedure of how the beam can be designed for a specific design bending moment. Consider the Eurocode 1992-1-1 and Finnish National Annex.

Based on the procedure, determine the number of T20 or T25 that the given cross-section below needs to withstand the design bending moment of 𝑀𝐸𝑑=300𝑘𝑁.𝑚.

The concrete class is C30/37 reinforced by B500 steel. The nominal cover is assumed to be 35mm and the stirrup is assumed to be T10. The given dimensions are in mm.
