live load surcharge on retaining walls

GUIDELINES FOR DETERMINING LIVE LOADS SURCHARGE FROM SIDEWALK.

traffic and street traffic for temporary shoring design adjacent to the public way. Surcharge loads shall be applied where vehicular load or pedestrian loads are expected to act on the surface behind a shored excavation or retaining wall within a distance equal to the height of the excavation or wall.【Get Price】

How loadings Applied to Retaining Wall

construction since it is the most critical section of wall stem in wall design. Steel has very high tensile strength but can bend easily due to its small cross section. Missing concrete or pool consolidation and foreign object intrusion in the wall base section will reduce support to the steel and can cause wall failure.【Get Price】

For now we will just take a look from a temporary works perspective and assess what effect a surcharge will have in terms of additional loads on the shoring that supports the wall. So let’s keep things simple for now and just consider a line load surcharge of say 10kN/m acting at the surface close to the excavation. According to classic.【Get Price】

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. Note that.【Get Price】
