The calculator will automatically estimate the number of cubic yards of concrete that will be required.
Concrete retaining wall calculation example.
Design the reinforced concrete masonry cantilever retaining wall shown in figure 2.
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.
1 2 example wall.
The following design example briefly illustrates some of the basic steps used in the allowable stress design of a reinforced concrete masonry cantilever retaining wall.

Example 3 16 design of a cantilever retaining wall bs 8 110 the cantilever retaining wall shown below is backþlled with granular material having a unit weight of 19 knm 3 and an internal angle of friction of 30.
In this example the structural design of the three retaining wall components is performed by hand.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
Because coming up short can be a disaster.
No shear key consider only friction between soil and concrete.
To respond successive editions have been updated corrections made and additional materials added.
This procedure is intended to be readily calculated by hand although use of calculation software such as mathcad or excel will be useful for design iterations.
Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Retaining wall terminology.
Density of concrete 24 kn m 3.
Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
F c 3000 psi fy 60 ksi o development of structural design equations.
Assume level backfill no surcharge or seismic loading active earth.
To use the concrete volume calculator simply enter the width length and thickness of your pour.
Assuming that the allowable bearing pressure of the soil is 120 knm 2 the coefþcient of friction is 0 4 and the unit.
Concrete cantilever wall example.
The base is divided into two parts the heel and toe.
Two equations are developed.
Concrete stem design.
The weight of the structure should be considered for this calculation as it increases the reaction that leads to a higher friction force.
F c 3000 psi fy 60 ksi natural soil development of structural design equations.
Design requirements for example and as we receive suggestions for topics to be added or expanded.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
The example calculations are made here using mathcad.
