Extend the vertical reinforcement steel bars beyond the top level of the lower storey.
Retaining wall steel reinforcement design.
Design procedure overview 3.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
These walls cantilever loads like a beam to a large structural footing converting horizontal pressures from behind the wall to vertical pressures on the ground below.
Calculate the development length for the steel reinforcement of the stem section of a concrete cantilever retaining wall.
Modular retaining wall systems there are three types of modular units used for retaining wall systems.
Forces on retaining walls 6.
The length of the extension should be equal to the required splice length specified by the design engineer or a minimum length of 40d where d diameter of smaller steel bar being spliced.
Cantilevered retaining walls are made from an internal stem of steel reinforced cast in place concrete or mortared masonry often in the shape of an inverted t.
Earthquake seismic design 7.
Soil bearing and stability 8.
Strength of reinforced concrete sections.
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.
Grade of rebar.
Hence provide h12 at 200 mm centres a s 566 mm 2 m in bottom face b of base and as distribution steel in base and stem of wall.
Reinforcement details the sketch below shows the main reinforcement requirements for the retaining wall.
Soil mechanics simplified 4.
For reasons of buildability the actual reinforcement details may well be slightly different.
Calculate the distance to steel and the area of the steel reinforcement for the toe section of the base of a concrete cantilever retaining wall.
Building codes and retaining walls 5.
Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971.
Today through technological advancements steel and geosynthetics are used for soil reinforcement to secure retaining walls bridge abutments parking area supports and landscape projects.
Calculate the lateral earth.
Stem steel development length.
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.
