Building codes and retaining walls 5.
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.
Strength reduced from 136 7 to 114 9 in kips.
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.
Pier and pile foundations 11.
Cantilevered tilt up walls 13.
Forces on retaining walls 6.
This type of walls has vertical stem monolithic with the base.
Heavy equipment shall maintain a distance away from the wall equal to the wall s height.
Gabion walls 16.
The heel is the part of the base under the backfill.
Wall types 1 2 7 and 8 may be used if no traffic barrier is attached on top of the wall.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Care shall be taken to avoid exerting large impact forces on the wall.
Designing the cantilever wall stem 9.
The base is divided into two parts the heel and toe.
Wood retaining walls 14.
Earthquake seismic design 7.
A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement.
Counterfort retaining walls 12.
Typical backfill and drainage detail.
Soil bearing and stability 8.
Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m.
