Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Two equations are developed in this.
Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond.
Soil mechanics simplified 4.
In this example the structural design of the three retaining wall components is performed by hand.
Forces on retaining walls 6.
In this example the structural design of the three retaining wall components is performed by hand.
Three different types of concrete masonry retaining walls are illustrated in figure 1.
F c 3000 psi fy 60 ksi o development of structural design equations.
Two equations are developed.
It is commonly used to separate.
The walls are used in a variety of applications se including right of way restrictions protection of existing structures that must remain in place.
This tek addresses unreinforced gravity retaining walls only.
They are the simple unreinforced vertical face gravity retaining wall the steel reinforced cantilever retaining wall and the segmental retaining wall.
Traditional retaining wall solutions can be expensive and restrictive for example cast in situ construction is slow and expensive to build and precast retaining wall panels are restricted in height.
Soil bearing and stability 8.
