Zones of stirrup distribution are defined for every span separately. Parameters of stirrup distribution along the beam length include:
- Distribution type
uniform 
3 distribution zones (denser spacing near supports) 
2 distribution zones - user-defined distribution - type the distribution definition in the s field: 4 * 200 + 5 * 300, dR is calculated automatically for the current span according to geometrical parameters
- Geometrical parameters, based on distribution type
- Uniform: stirrup spacing s, distance of the first/last stirrup from the left/right support
- 3-zone: stirrup spacing s in each zone, distance of the first/last stirrup from the left/right support
Note: You can generate additional stirrups above supports at the beginning/end of the beam (after Left support or Right support is selected).
