Design Defaults
New setting Design defaults is created in menu Concrete > Reinforcement design, where user can define defaults parameters for design of reinforcement including provided reinforcement. This functionality allows to define basic setting and library of provided reinforcement depending on type of member and cross-section for whole structure. Main goal is to define basic and additional reinforcement for design for whole structure in project according to the type of member and cross-section.
The group Reinforcement design and dialog Design defaults will be visible, even the calculation is not done. The setting in dialog Design defaults will be similar as Concrete setting.
When you open design defaults dialogue you can see there defaults based on the member type.
Beam (Rib)
The possibilities in Design defaults dialogue are dependent on the usage or not of provided library for longitudinal reinforcement.

- Only upper and lower surface cover is defined (No side cover)
- Only link provided reinforcement library for Rectangular cross-section
- Without definition of stirrups
When the provided reinforcement library is used then diameters for design are defined in provided reinforcement library directly.
When the provided reinforcement library is not used then diameters for design are defined in design defaults directly.

Note: Directions of designed reinforcement, in general independent for the upper and lower surface of the member, can be visualized by symbolic arrows (single arrow for each direction) using the option [Drawing directions for design] in View parameters setting. The arrows are drawn per member or individually for each mesh element, depending on the selected local coordination system of the member. If the LCS is the same for all mesh elements, then the arrows are drawn only once for the whole member near the centre of gravity. Moreover, when results related to specific reinforcement direction are presented, only the arrow associated with this direction and surface is automatically drawn. The visualization of the arrows can be modified by Colours/Lines settings to distinguish each direction specifically for better orientation in results.
