Concrete block retaining wall design example.

Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. Movement of the retaining wall. Over its intended service life other loads may also be applied to the structure.

Some of the advantages of using large precast concrete block systems for retaining structures include. The wedge is defined as the soil which extends beyond the failure. Setback sliding wedge. Let s take a fresh look and see how concrete interlocking blocks or more commonly known as concrete lego blocks can be used as the solution.

Pile design example. Conditions and wall geometry n a design example which demonstrates the use of the australian standard and analysis method n analysis of cohesive soils. 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. Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.

Despite the many references a single volume on retaining wall design for the professional practitioner and civil engineering student could not be found. Design the reinforced concrete masonry cantilever retaining wall shown in figure 2. The coefficient of friction between the footing and foundation soil k 1 is 0 25 and the allowable soil bearing pressure is 2 000 psf 95 8. Hence this attempt to condense simplify and compile information from many.

In this example the structural design of the three retaining wall components is performed by hand. Every retaining wall supports a wedge of soil. In this example the structural design of the three retaining wall components is performed by hand. F c 3000 psi fy 60 ksi natural soil development of structural design equations.

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. Two equations are developed. Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article retaining wall.

For retaining wall applications the structure must be designed to resist the forces from the retained material acting on one side of the wall. A retaining wall that relies solely on it s own weight to stand up is called a gravity wall allan block combines the basic engineering principles of setback leverage and total unit mass with simple mechanics to make highly stable gravity walls.
