To define the parameters of adjoining bars when calculating the buckling coefficient of the main bar, double-click 
, in the Buckling Diagrams dialog.
Enter the following information for the main bar:
- The number of the consecutive structural bars (the section of the selected structural bar is automatically entered); enter the bar number in the appropriate field or select the bar on the screen.
- Position (placement) of the bar in the structure; two methods are possible: vertical
or a horizontal 
.
For several codes (ADD8, Eurocode3, NEN6770/6771, PN90) another parameter is included: the support method for the other end of the adjoining bar. The available support types for the opposite end depend on the selected steel code requirements.
Once the adjoining bar of a selected number is in place, the buckling coefficient value is displayed in the lower portion of the dialog. The value of the buckling coefficient is displayed in the Test for Bar: Value field once the adjoining bar number is selected.
To manually define the parameters of adjoining bars, press the Manual button found in the lower part of the dialog. The manual definition of adjoining bar parameters is displayed on the screen.
To define parameters of varying inertia bars, press the Parameters button, and enter the information on the additional dialog.
