Reinforced Concrete Design ACI / CAN/CSA - Calculation Settings

 

Depending on the selected standard, the Calculation Settings dialog box allows the definition of the concrete calculation settings.

 

How to access the command

Standard settings

This tab defines the reinforced concrete calculation settings.

Planar elements calculation method

Defines the reinforcement calculation method for the planar elements:

Note

If the membrane forces are null or irrelevant, the Wood method is used. This calculation procedure allows the evaluation of bending moments starting from Mx, My and Mxy to determine the sections of each reinforcement level. If the membrane forces are significant, the Capra method is used because it takes into account the tension and compression membrane forces. The Capra method is also used in case of combined tension, because the Wood method extension considering the membrane forces leads to exceeded reinforcement when the shell is subjected to compression.

Buckling

This tab defines the type of structure for the buckling lengths calculation by Ka Kb coefficients. For xy and xz planes it can be specified if the structure has braced or unbraced nodes. If these options are disabled, there is no specification for the structure's stability and the buckling lengths are calculated by the local parameters of each element.

Note

The settings made in this tab do not affect the elements whose properties are defined by design templates. In this case, the element design properties are linked to the corresponding template.

Reinforcement settings

This tab contains the list of reinforcements from which the concrete expert may suggest at the end of the concrete calculation. Only the selected reinforcements are considered in the concrete design calculation.

Reinforcement settings

Use the selection boxes from the Longitudinal / Transversal columns to specify the reinforcements to consider.

You can also use the All / None options to select or unselect all the available options.

Select the desired system: Metric / Imperial.

Calculation Sequence

This tab defines the verifications to perform during the reinforced concrete calculation.

Note

For CAN/CSA standard you can also enable Punching verification for the punching verification of slabs.
