Dear Philipova,

First of all, you should use the correct "Standard" or "Norm" in the option of engineering module.

At the moment, you are in "DIN EN", which is the Euronorm with German appendix.

You can set it to:

BS EN
BS 8666

And maybe some other.

Than you have the possibility to use the steel grade to B500B.

But take care because you catalog of bars and mesh is maybe in german.

So you must also load the englisg catalog for reinforcement.

To do that, you must create a project with the reinforcement setting define in "Projet" (if not you will change all project).

Than click to Tools / Default and open the cross section catalog.

In this windows, you can load any catalog from other country by clicking in "read" and search the correct data. All country reinforcement are saved in the folder "C:\Program Files\Nemetschek\Allplan2019\New\Ing" and choose the file "aengqusr.txt".

Bye & Good Use!
