Retaining Wall Steel Reinforcement Design

For reasons of buildability the actual reinforcement details may well be slightly different.

Retaining wall steel reinforcement design.

Earthquake seismic design 7. Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance. Reinforcement details the sketch below shows the main reinforcement requirements for the retaining wall. Construction sequence animation showing the reinforcement arrangement for a single retaining wall panel.

The base is divided into two parts the heel and toe. And the strength steel is installed with a. 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. 3500 psi concrete 5 10.

Strength of reinforced concrete sections location of strength rebar relative to compressive face of concrete d the project calls for. Clear cover of 3 inches. Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971. Determining the reinforcing steel schedule whether vertical or horizontal is a structural engineering task which depends on many factors.

Design procedure overview 3. This is beyond the scope of this technical manual however some tools are available for the residential construction market to assist in reinforcing steel design. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. 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.

Clear cover of 2 inches. Soil mechanics simplified 4. 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. 3 clear rather than the designed 2 clear.

Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article retaining wall. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. As shown by the blue box by adding a geosynthetic reinforcement to the soil the srw system becomes a composite system made up of the wall units the soil and the geogrid. 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.
