The Longitudinal reinforcement tab of the Calculation Parameter Definition dialog box for the Chinese code GB 50010-2002:
In the top part of a dialog box, data about parameters of reinforcing steel can be determined. It can be completed by either choosing the appropriate steel grade or giving fyk strength.
Below, diameters of bars for reinforcement of an element are determined. The bars are listed in metric diameter units for top/bottom reinforcement. 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.
