Concrete retaining wall calculation example.

In this example the structural design of the three retaining wall components is performed by hand. Weight of the structure 3 9 0 4 2 6 0 5 x24. The example wall is shown in figure x 2. 1 2 example wall.

Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. 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. Two equations are developed in this. The calculator will automatically estimate the number of cubic yards of concrete that will be required.

The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. 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. F c 3000 psi fy 60 ksi natural soil development of structural design equations.

Density of concrete 24 kn m 3. The weight of the structure should be considered for this calculation as it increases the reaction that leads to a higher friction force. Retaining wall terminology. Assume level backfill no surcharge or seismic loading active earth.

The base is divided into two parts the heel and toe. Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. The example calculations are made here using mathcad. 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.

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. Concrete wall calculator avada1start 2018 12 20t15 19 03 04 00 concrete wall calculator. Concrete stem design.

Assuming that the allowable bearing pressure of the soil is 120 knm 2 the coefþcient of friction is 0 4 and the unit. Two equations are developed. Design requirements for example and as we receive suggestions for topics to be added or expanded. Concrete cantilever wall example.

Because coming up short can be a disaster. No shear key consider only friction between soil and concrete. 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.
