Design a reinforced concrete retaining wall for the following conditions.
Retaining wall reinforcement design example.
Design the reinforced concrete masonry cantilever retaining wall shown in figure 2.
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.
Design procedure overview 3.
Assume level backfill no surcharge or seismic loading active earth.
In this example the structural design of the three retaining wall components is performed by hand.
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 base is divided into two parts the heel and toe.
F c 3000 psi fy 60 ksi o development of structural design equations.
Two equations are developed in this section for determining the thickness reinforcement required.
Assuming that the allowable bearing pressure of the soil is 120 knm 2 the.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
