The Longitudinal reinforcement tab from the Definition of calculation parameters dialog for ACI 318/95 code or ACI 318/95 metric code:
At the top of the dialog, parameters of reinforcing steel data are defined. These can be entered by either choosing the appropriate steel grade or entering fy resistance.
Bar diameters used to reinforce elements can be determined. If the Use types according with ASTM option is selected on the General tab then ASTM bars are accessible. Otherwise, a diameter list in metric units is accessible. Bar diameters can be different for top and bottom reinforcement of a beam. Similarly, a column can have reinforcement along h and b sides. If the same diameters are used for the entire element, the same type of reinforcement in both directions option should be selected.
At the bottom part of the dialog, reinforcement cover can be defined. The cover can be calculated as a cover to axis or clear cover of bottom reinforcement. Cover values are converted automatically.
