Use this option to enable a more exact definition of the reinforcement distribution method. After selecting the Distribution options tab, the Reinforcement: definition and detailing - radial reinforcement dialog displays:
The left side of the dialog box contains three icons:
- for this type no parameters are determined: a whole distribution surface is covered evenly with bars.
- defines a passing distribution: every second bar extends from edge to edge, while the remaining ones end in an appropriate distance from the edge; middle bars are always straight bars; two edit fields allow defining the length of middle bars and the additional icon between the edit fields is used for exchanging the arrangement.
- defines a passing distribution: distributed bars are of the same shape, however, they are shifted with respect to each other; if there is an opening (in the zone near the support), use of this distribution type is not justified, the uniform distribution is applied then.
The support width option is inaccessible; it is used when defining distributions above supports.
There are two ways to define the polar distribution (distributing lap splices of bars in the polar distribution):
- Uniform division (see the drawing below)
- Division using the maximum length of a bar (see the drawing below).
Each bar in the polar distribution is divided separately following the rule: bar of the maximum length + bar of the maximum length + the rest resulting from the remaining length of a bar to be distributed. Division of every bar in the polar distribution starts at the same point.
