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.

Longitudinal reinforcement

Displaying of items in Design defaults for Beams is dependent on setting Use a template of provided reinforcement

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.
