Recommended stem designs for reinforced cantilever retaining walls with no surcharge are contained in tables 1 and 2 for allowable stress design and strength design respectively.
Cantilever retaining wall reinforcement design.
Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
It is constructed of reinforced portland cement.
Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage.
The base is divided into two parts the heel and toe.
Retaining walls 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.
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.
It has much thinner stem and utilize the weight of the backfill soil to provide most of the resistance to sliding and overturning.
Cantilever retaining wall is the most common type of earth retaining structure.
It is the length from face of the wall stem to rear end of the base slab which includes the thickness of stem.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
These design methods are discussed in detail in allowable stress design of concrete masonry tek 14 7a and strength design of concrete masonry tek 14 4a refs.
