Retaining Wall Steel Reinforcement Design

Reinforced retaining wall this is a cross section of a reinforced wall.

Retaining wall steel reinforcement design.

Forces on retaining walls 6. Clear cover of 3 inches. Earthquake seismic design 7. Reinforcement details the sketch below shows the main reinforcement requirements for the retaining wall.

Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. And the strength steel is installed with a. 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. 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.

This composite system provides stability to the retaining wall allowing architects to increase wall. Clear cover of 2 inches. 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.

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. 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. For reasons of buildability the actual reinforcement details may well be slightly different. Construction sequence animation showing the reinforcement arrangement for a single retaining wall panel.

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. The base is divided into two parts the heel and toe. 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 design 10 editionth a design guide for earth retaining structures contents at a glance. Determining the reinforcing steel schedule whether vertical or horizontal is a structural engineering task which depends on many factors. 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. 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.

Building codes and retaining walls 5. Soil mechanics simplified 4. Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
