The Transversal reinforcement tab of the Definition of calculation parameters dialog box for BS Code:
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 fy resistance.
Either stirrups or spirals may be chosen for Transversal reinforcement. Presently, spiral reinforcement is not available.
At the bottom of the dialog, parameters of stirrup reinforcement are defined.
Use the Take longitudinal reinforcement into consideration option to consider longitudinal reinforcement during calculation of a transversal reinforcement area. It decreases the transversal reinforcement area because longitudinal reinforcement is provided.
