This post will focus on the design of reinforced concrete cantilever walls.
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.

This session is not intended to teach concrete design but more of an awareness of why things are the way they are american concrete institute building code requirements for structural concrete aci 318 which is referenced in nrcs.
Provide the distribution steel.
Reinforced concrete wall design basics mike o shea p e.
Design the wall and base reinforcement assuming fcu 35 knm 2 f y 500 knm 2 and the cover to reinforcement in the wall and base are respectively 35.
The base is divided into two parts the heel and toe.
Determine the factors of safety against sliding and overturning.
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.
As a result it is also known as gravity retaining wall.
Design example cantilever retaining wall.
In instance of masonry retaining wall the thickness of wall enhances with height for the reason that masonry opposes the lateral pressure by its mass.
Forces on retaining walls 6.
Also check for shear at the junction.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Provide enough development length.
There are three different forms of this type of wall all of which are designed to resist overturning and sliding failure.
Cantilever retaining wall rcc inverted t and l.
Although retaining wall was the subject of the last post their design was not covered.
The primary difference between them is their height.
