Retaining Wall Steel Reinforcement Design

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.

Retaining wall steel reinforcement design.

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. Soil mechanics simplified 4. 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. Designing reinforcing steel for walls.

Earthquake seismic design 7. 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. Clear cover of 3 inches. Design procedure overview 3.

Clear cover of 2 inches. Building codes and retaining walls 5. Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance. For reasons of buildability the actual reinforcement details may well be slightly different.

Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. It is extensively used in variety of situations such as highway engineering railway engineering bridge engineering and irrigation engineering. Determining the reinforcing steel schedule whether vertical or horizontal is a structural engineering task which depends on many factors. Soil bearing and stability 8.

Forces on retaining walls 6. 3 clear rather than the designed 2 clear. 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. 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.

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. The base is divided into two parts the heel and toe. 3500 psi concrete 5 10. Reinforcement details the sketch below shows the main reinforcement requirements for the retaining wall.

Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971. Strength of reinforced concrete sections location of strength rebar relative to compressive face of concrete d the project calls for. A retaining wall is one of the most important types of retaining structures.
