The option is used for manual modification of the spacing of stirrups (in beam 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 a support face from the left or from the right side (depending on a selected description method) with respect to the most extreme element selected.
After modifying transversal reinforcement, the program starts automatically reinforcement verification.
