B.1.3 Reinforcement Steel

Via the Reinforcement steel concept you may specify predefined reinforcement steel classes [§10.3]. Via subconcepts you may specify the code, the class and other topics.

B.1.3.1 Dutch Code

The NEN 6720 concept indicates reinforcement steel according to the Dutch code [§10.3.1]. You must choose a class FeB n for embedded steel [Table 10.4], or FeP n for prestress cables [Table 10.5]. You must also indicate whether or not the reinforcement is bonded to the surrounding material. Furthermore, you may indicate the application of a hardening plasticity model. Depending on the steel class and the specified concepts for elastic or plastic behavior iDIANA shows the predefined values for the various properties.
