Assume level backfill no surcharge or seismic loading active earth.
Concrete retaining wall calculation example.
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.
The calculator will automatically estimate the number of cubic yards of concrete that will be required.
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.
F c 3000 psi fy 60 ksi natural soil development of structural design equations.
In this example the structural design of the three retaining wall components is performed by hand.
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.
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.
No shear key consider only friction between soil and concrete.
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.
Two equations are developed in this.
To respond successive editions have been updated corrections made and additional materials added.
The example calculations are made here using mathcad.

Design requirements for example and as we receive suggestions for topics to be added or expanded.
To use the concrete volume calculator simply enter the width length and thickness of your pour.
Density of concrete 24 kn m 3.
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.
Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.

Because coming up short can be a disaster.
Weight of the structure 3 9 0 4 2 6 0 5 x24.
The weight of the structure should be considered for this calculation as it increases the reaction that leads to a higher friction force.
