6.5 Summary of key points

Limit states STR and GEO involve failure or excessive deformation of the structure or ground, in which the strength of the structure or ground is significant in providing resistance.

Verification of these limit states is demonstrated by satisfying the inequality:

Ed < Rd in which Ed = design effects of actions and Rd = design resistance. This equation is applied using one of three Design Approaches, chosen in the National Annex.
