| Table of cross-section parts (bottom left) |
| Setting | Description |
|---|
| Part |
Number of the cross-section part |
| Type |
Type of the cross-section part
- Static: The part is effective for the stiffness calculation
- Weight: The part is only considered for calculating the self-weight of the members.
- Slave: The cross-section part is not a physical part but a fictitious part describing the position of a so-called slave node with separate degrees of freedom. These DOF's are used in the case of a Finite Element analysis with using shell or volume elements for giving allowance to deformation of the cross-section.
|
| Cls |
Class of the cross-section part. This class term refers to the cross-section categories of table 6.2 of Eurocode EN 1993-1-1. It is used in steel design checks for selecting the relevant buckling curve and for calculating the cross-section class with respect to local buckling hazard (cross-section classes 1 to 4 in Eurocode or classes "Compact", "Non-compact" and "Slender" in AASHTO code).
- Solid: General, more or less compact section, which does not belong to a special class as defined below (also C profiles (channels) and T profiles).
- I-R (I-rolled): Rolled I or H profile.
- I-W (I-welded): Welded I or H profile.
- L (I-rolled): Rolled angle profile (equal or unequal legs)
- BRh (Box rolled hot): Hot rolled hollow profile (rectangular box or pipe)
- BRc (Box rolled cold): Cold rolled hollow profile (rectangular box or pipe)
- BW (Box welded general): General welded hollow box profile
- BWs (Box welded special): Welded hollow profile with thick walls and welds
