The Live Load Surcharge is positioned to produce the maximum design load. In Figure 1 where a semi-gravity wall is shown the Live Load Surcharge is placed over any element of the ERS for settlement and bearing analysis while the Live Load Surcharge is placed behind all the elements of the ERS for sliding and eccentricity analysis.
