By using the minimum reinforcement, the tensile stress, which was absorbed by the concrete before in the event of initial crack formation, should be covered by a reinforcement.
The minimum area of the longitudinal tension reinforcement is calculated according to EN 1992-1-1 [1] 9.2.1.1(1). Die Querschnittsfläche der Zug- oder Druckbewehrung wird nach Absatz 9.2.1.1(3) begrenzt.
