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.
The system s soil reinforcements are inextensible high adherence ha steel reinforcing strips or ladders which are bolted to tie strips embedded in precast concrete facing panels.
The base is divided into two parts the heel and toe.

Cut the vertical reinforcement steel bars for the lower storey so that they are flush with the top of that wall.
Calculate the development length for the steel reinforcement of the stem section of a concrete cantilever retaining wall.
Calculate the lateral earth.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
