Retaining Wall Steel Reinforcement Design

A retaining wall is one of the most important types of retaining structures.

Retaining wall steel reinforcement design.

Construction sequence animation showing the reinforcement arrangement for a single retaining wall panel. Design procedure overview 3. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. The base is divided into two parts the heel and toe.

Building codes and retaining walls 5. 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. 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. Earthquake seismic design 7.

Determining the reinforcing steel schedule whether vertical or horizontal is a structural engineering task which depends on many factors. 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. Designing reinforcing steel for walls. Clear cover of 3 inches.

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. Soil mechanics simplified 4. 3 clear rather than the designed 2 clear. 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.

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. Clear cover of 2 inches. Forces on retaining walls 6. Strength of reinforced concrete sections location of strength rebar relative to compressive face of concrete d the project calls for.

The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971. For reasons of buildability the actual reinforcement details may well be slightly different.
