Setting Description

Tolerance of rectilinearity

The calculation of the effective width of composite beams is only performed if they lie within the tolerance on rectilinearity adjusted here.

The default tolerance is 15 degrees. At greater angles, you will be prompted to type the effective width manually.

Update effective width prior to design check

Allows you to determine the effective width each time auto or check design is run.

Note: Unless this box is selected, you will be unable to manually override the effective width on the Floor construction and Natural frequency pages of the beam properties.
Transverse reinforcement
Minimum bar size (auto-selection) Sets the minimum allowable bar size that can be used in the transverse bar auto-select process. (Applies only to bar reinforcement and not to mesh.)
Note: This option is available for Eurocode and British Standard regional codes only.
Maximum bar size (auto-selection) Sets the maximum allowable bar size that can be used in the transverse bar auto-select process. (Applies only to bar reinforcement and not to mesh.)
Note: This option is available for Eurocode and British Standard regional codes only.
