Longitudinal reinforcement can be designed to more edges of cross-section and for general cross-section. Designed required area is for better overview and graphical presentation recalculated to directions of axis’s of LCS of the cross-section (member). The recalculation area of reinforcement depends on angle of edge from y-axis and angle of bending moment resultant from y-axis, see pictures below. It follows, that 4 areas of reinforcement can be presented in graphical and numerical output:
| Asz.req+ | required area of reinforcement (mostly designed for bending moment My) placed on edges above axis y with angle of edges lesser than 45 ° from y-axis. The edges with angle 45 ° and above axis y are assigned to this direction if direction of bending moment resultant (αM) is lesser or equal than 45 °. |
| Asz.req- | required area of reinforcement (mostly designed for bending moment My) placed on edges under axis y with angle of edges lesser than 45 ° from y-axis. The edges with angle 45 ° and under axis y are assigned to this direction if direction of bending moment resultant (αM) is lesser or equal than 45 °. |
| Asy.req+ | required area of reinforcement (mostly designed for bending moment Mz) placed on edges above axis z with angle of edges greater than 45 ° from y-axis. The edges with angle 45 ° and above axis z are assigned to this direction if direction of bending moment resultant (αM) is greater than 45 °. |
| Asy.req- | required area of reinforcement (mostly designed for bending moment Mz) placed on edges under axis z with angle of edges greater than 45 ° from y-axis. The edges with angle 45 ° and under axis z are assigned to this direction if direction of bending moment resultant (αM) is greater than 45 °. |
Note: Same procedure is used also for recalculation of provided (As,prov) reinforcement to directions.
