There are some values in design of reinforcement, which are dependent on area of reinforcement, for example:
These values should be calculated before design of reinforcement, but before design we do not know area of reinforcement. It follows that for calculation of this value
The third solution is implemented in SCIA Engineer via parameter Estimation ratio of longitudinal reinforcement for recalculation internal forces, where user can set ratio of reinforcement, which will be used for calculation of the values above.This value can be set in Concrete settings, see "Concrete settings" by using Advanced level or in 1D member data (advanced mode is ON), if is defined. Total area of reinforcement is calculated according to formula:
As = μs ∙ Ac
where
| Ac | cross-sectional area of concrete cross-section |
| μs | estimation ratio of longitudinal reinforcement loaded from Concrete setting (if concrete member data is not defined ) or concrete member data |
