5.5.5.3 Load Combinations
The load combinations for deformation-controlled and force-controlled actions
are listed in Table 5.7.

5.5.6 Overturning Effects

The overturning effects shall be resisted through the stabilizing effect of dead
loads acting alone or in combination with positive connections of structural
components to components below the level under consideration. Where dead
loads alone are used to resist the effects of overturning, Eq. (5.18) shall be
satisfied:
