Reinforcement material - ductility
Settings
The recommended classes of non-prestressed reinforcement for concrete bridges are B and C only according to article 3.2.4(101). Reinforcement A is not recommended at all for EN 1992-2. Allowed ductility setting is implemented in Concrete > General > Nonprestressed reinforcement.
Implementation
Therefore when the reinforcement class A is used then the following message appears. This limitation is done in all concrete checks.
W920 – The used non-prestressed reinforcement is not allowed due to low ductility
