Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Poured concrete gravity retaining wall design example.
Two equations are developed in this.
Two equations are developed.

Restrained non yielding walls 20.
In this example the structural design of the three retaining wall components is performed by hand.
Construction topics and caveats 24.
Flexural and shear stresses are checked in the second design example and it is seen that the magnitudes are very low.
The failures also clearly demonstrate the lack of knowledge or design that is required by a successful retaining wall design.
Flexural and shear stresses in gravity retaining walls will almost always be of minor importance.

How retaining walls fail.
Cantilever retaining wall reinforced concrete wall with small dimensions and it is the most economical type and the most common note.

Soldier pile walls 22.
By understanding how a wall works and how it can fail it is possible to engineer a retaining structure that will meet all foreseen environmental structural and construction demands.
Semi gravity retaining wall reduce the dimensions of the gravity retaining wall by using some reinforcement.
For example if you are pouring a retaining wall that will be 12 inches thick and will use wooden planks that are 1 1 2 inches thick for your forms you ll need to space the stakes about 15 inches apart 12 inches for the retaining wall plus two pieces of 1 1 2 inch thick wooden board.
Structural design of cantilever retaining wall is depend on separating each.

Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
