Columns: the minimum area of longitudinal reinforcement following the EN Eurocode recommendation, As,min
Eurocode 2 part 1-1: Design of concrete structures 9.5.2 (2)
The recommended value for the minimum area reinforcement As,min is:
|As,min = (0,10 NEd)/fyd ≥ 0,002 Ac||(9.12N)|
- is the design axial compression force
- is the design yield strength of the reinforcement, fyd = fyk/γS
see § 18.104.22.168 (1) for the values of γS,
see § 3.2.2 (3)P for the uper limit of fyk
- is the area of concrete cross section.
This application calculates the minimum area of reinforcement As,min from your inputs.
