The use of wsdot standard plan reinforced concrete retaining walls and traffic barrier details for reinforced concrete retaining wallsshall be limited as follows.
Reinforced concrete retaining wall detail.
Wall types 1 2 7 and 8 may be used if no traffic barrier is attached on top of the wall.
The base is divided into two parts the heel and toe.
Typical backfill and drainage detail.
A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement.

Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m.
Earthquake seismic design 7.
Forces on retaining walls 6.
2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16.
This type of walls has vertical stem monolithic with the base.
Designing the cantilever wall stem 9.
Building codes and retaining walls 5.
Strength reduced from 136 7 to 114 9 in kips.
Soil bearing and stability 8.
Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
Heavy equipment shall maintain a distance away from the wall equal to the wall s height.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
