The result tables of the Buckling Analysis category display the stability design checks of the analyzed joints.
Node
The results are displayed for each node of a joint. The list is sorted by load combination.
Mode Shape
For each node, as many mode shapes ("buckling modes") are analyzed as you have defined as the "Number of Lowest Eigenvalues" in the Ultimate Configuration .
Critical Load Factor f
This column shows the critical load factors. They indicate the factor by which the existing load must be multiplied in order for a stability failure to occur at the node.
