Retaining Wall Steel Reinforcement Design

Today through technological advancements steel and geosynthetics are used for soil reinforcement to secure retaining walls bridge abutments parking area supports and landscape projects.

Retaining wall steel reinforcement design.

Building codes and retaining walls 5. Strength of reinforced concrete sections. 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. 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.

Concrete strength al ൯ne for an 10 thick wall with 5 10 and 2 5 clear to strength steel will only reduce the nominal moment capacity of the secti對on from 136 68 to 135 66 inch kips 尩 if the concrete strength decreased from 3 5 to 3 0 ksi. For reasons of buildability the actual reinforcement details may well be slightly different. Stem steel development length. 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.

Calculate the development length for the steel reinforcement of the stem section of a concrete cantilever retaining wall. 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. Soil mechanics simplified 4. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.

Modular retaining wall systems there are three types of modular units used for retaining wall systems. Calculate the lateral earth. Design procedure overview 3. Earthquake seismic design 7.

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. Forces on retaining walls 6. 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.

Reinforced earth is the reinforced earth company s flagship mse retaining wall product first introduced in the united states in 1971. Grade of rebar. Soil bearing and stability 8. Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance.
