In the American design of a concrete beam, you are able to turn off the use of Shear Reinforcement because the concrete will take the shear load. See here:
In the European design, there is no way to turn off the shear stirrups that I can see.
Thanks again for your message @Msouth . According to the EN 1992.1.1 Cl. 6.2.1 (4) minimum shear reinforcement is always required, please see below. That’s why we always consider stirrups.
I hope that clarifies!
