Strength reduced from 136 7 to 114 9 in kips.
Reinforced concrete retaining wall detail.
Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m.
Soil bearing and stability 8.
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.
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 heel is the part of the base under the backfill.
The base is divided into two parts the heel and toe.
Designing the cantilever wall stem 9.
Counterfort retaining walls 12.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement.
Typical backfill and drainage detail.
Backfilling against reinforced masonry retaining walls shall not be permitted until at least 7 days after placing concrete or grout in cores.
The use of wsdot standard plan reinforced concrete retaining walls and traffic barrier details for reinforced concrete retaining wallsshall be limited as follows.
Pier and pile foundations 11.
Wood retaining walls 14.
Building codes and retaining walls 5.
Gabion walls 16.
This type of walls has vertical stem monolithic with the base.
Earthquake seismic design 7.
Care shall be taken to avoid exerting large impact forces on the wall.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
