In the Reinforcement tab, you can select the material for the reinforcement using the drop-down menu in the "Material" section. In this case, it is possible to select a suitable material, such as B500S(A), for the reinforcement of the foundation plate and the block.
The reinforcement properties of the foundation plate are described in the chapters Reinforcement and Plate Reinforcement.
In addition to the foundation plate, it is necessary to define the reinforcement properties of the block.
