2.13.5 Verification of stability for limit state EQU

Figure 2.22 combines the earlier flow diagrams for limit state EQU. Destabilizing actions (characteristic ^ representative ^ design) are on the left; geometrical parameters (nominal ^ design) in the centre; and stabilizing actions (representative ^ design) on the right. The introduction of combination factors partial factors y, and tolerances Aa at appropriate points in this process is shown.

Structural analysis uses design actions (destabilizing and stabilizing) and design dimensions to determine destabilizing and stabilizing design effects of actions.

Limit state EQU is verified when destabilizing design effects are less than or equal to stabilizing design effects.
