Summary of key points

The design of gravity walls to Eurocode 7 involves checking that the ground beneath the wall has sufficient bearing resistance to withstand inclined, eccentric actions, sufficient sliding resistance to withstand horizontal and inclined actions, sufficient stability to avoid toppling, and sufficient stiffness to prevent unacceptable settlement or tilt. The first three of these guard against ultimate limit states and the last against a serviceability limit state.

Verification of the ultimate limit states is demonstrated by satisfying the inequalities:

^d < Rd, and Hd < Rd + Rpd, and Me,m < Me,,sft

(where the symbols are defined in Section 10.3). These equations are merely specific forms of:

Ed < Rd which is discussed at length in Chapter 6.
