The option is used for manual modification of the spacing of stirrups (in column transversal reinforcement). It is available after selecting the Reinforcement / Stirrup Spacing command from the menu.
The above dialog box displays a description for selected elements in the following format:
n1*e1 + n2*e2 +… ,
where:
n1, n2, ... - number of stirrups
e1, e2, ... - stirrup spacing.
As a zero point the program assumes the bottom or top part of a column (depending on a selected description method).
After modifying transversal reinforcement, the program runs automatically reinforcement verification.
