Cross-Section Data
Use the Cross-Section Data node to describe the section for the truss elements on the selected edges.
Cross-Section Data
Enter the cross-section Area A.
This is required input data.
Local Buckling
Optionally, you can also provide data that makes it possible to assess the risk of local buckling of the individual bars in the structure.
Enter the Smallest principal moment of inertia, Imin. This is the area moment of inertia in the weakest direction of the cross section.
Enter the Effective length factor, K. This is a multiplier to the physical length of the bars, intended for compensating for end conditions. The default value, 1, corresponds to a pure Euler 2 buckling case.
