Pier and pile foundations 11.
Reinforced concrete retaining wall detail.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
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 types of retaining wall are recommended for heights up to 7 m.
Typical backfill and drainage detail.
Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
Soil bearing and stability 8.
Heavy equipment shall maintain a distance away from the wall equal to the wall s height.
Forces on retaining walls 6.
Cantilevered tilt up walls 13.
The use of wsdot standard plan reinforced concrete retaining walls and traffic barrier details for reinforced concrete retaining wallsshall be limited as follows.
The base is divided into two parts the heel and toe.
Wood retaining walls 14.
Care shall be taken to avoid exerting large impact forces on the wall.
Wall types 1 2 7 and 8 may be used if no traffic barrier is attached on top of the wall.
Designing the cantilever wall stem 9.
Counterfort retaining walls 12.
Earthquake seismic design 7.
Gabion walls 16.
A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement.
Strength reduced from 136 7 to 114 9 in kips.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Backfilling against reinforced masonry retaining walls shall not be permitted until at least 7 days after placing concrete or grout in cores.
