ACI Code

For American ACI code the following calculations are performed:

Beams

• Calculation of theoretical (required) reinforcement area as for ULS.
• Checking (correction) reinforcement for cracking (a simplified method that does not need SLS calculations).
• Calculation of theoretical (required) stirrups spacing for shear forces.
• Re-calculation of theoretical (required) area to a bar number.
• Re-calculation of theoretical (required) stirrups spacing to a modular spacing in a given number of equal sections.

Columns

• Calculation of theoretical (required) reinforcement area for ULS taking into consideration slenderness for sway and non- sway frames.
• Calculation of theoretical (required) stirrups spacing.
• Re-calculation of theoretical (required) stirrups spacing to a modular spacing at the length of a column.
