Concrete Retaining Wall Calculation Example

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

Concrete retaining wall calculation example.

Assume level backfill no surcharge or seismic loading active earth. Assuming that the allowable bearing pressure of the soil is 120 knm 2 the coefþcient of friction is 0 4 and the unit. 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. Design requirements for example and as we receive suggestions for topics to be added or expanded.

To respond successive editions have been updated corrections made and additional materials added. In this example the structural design of the three retaining wall components is performed by hand. Density of concrete 24 kn m 3. The example wall is shown in figure x 2.

Two equations are developed in this. Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. Concrete wall calculator avada1start 2018 12 20t15 19 03 04 00 concrete wall calculator. Weight of the structure 3 9 0 4 2 6 0 5 x24.

Because coming up short can be a disaster. Concrete stem design. 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. The calculator will automatically estimate the number of cubic yards of concrete that will be required.

Two equations are developed. Concrete cantilever wall example. To use the concrete volume calculator simply enter the width length and thickness of your pour. No shear key consider only friction between soil and concrete.

Design the reinforced concrete masonry cantilever retaining wall shown in figure 2. 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. 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.

The base is divided into two parts the heel and toe. In this example the structural design of the three retaining wall components is performed by hand. 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.

1 2 example wall. Retaining wall terminology. The weight of the structure should be considered for this calculation as it increases the reaction that leads to a higher friction force.
