Reinforcement Counterfort Retaining Wall Design

Design procedure overview 3.

Reinforcement counterfort retaining wall design.

1 gravity wall masonry or plain concrete 2 cantilever retaining wall rcc inverted t and l 3 counterfort retaining wall rcc 4 buttress wall rcc. Designing the cantilever wall stem 9. Preliminary proportioning of counterfort retaining wall. Thickness of heel slab and stem 5 of height of wall.

They consist of a relatively thin stem and a base slab. Earthquake seismic design 7. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. Classification of retaining walls.

The main reinforcement is provided horizontally along the length of the wall. Counterfort retaining wall rcc. Design of counterfort retaining wall. Counterfort walls are cantilever walls strengthened with counter forts monolithic with the back of the wall slab and base slab.

Design example cantilever retaining wall. Building codes and retaining walls 5. Soil mechanics simplified 4. In no case thickness of any component be less than 300mm.

The heel is the part of the base under the backfill. The base is also divided into two parts the heel and toe. Also check for shear at the junction. Pier and pile foundations 11.

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. Soil bearing and stability 8. The ties are provided horizontally for the full value of reaction to prevent slab separating from counterforts. The loads that are of primary concern are the lateral earth pressures induced by the retained soil.

Provide the distribution steel. The counter forts act as tension stiffeners and connect the wall slab and the base to reduce the bending and shearing stresses. Forces on retaining walls 6. Under normal conditions the lateral earth pressure is at rest condition.

Thickness of counterfort 6 of height of wall. Counterfort retaining walls 12. The toe is the other part of the base. Provide enough development length.

This excel sheet introduces design of counterfort retaining wall according. Design of toe slab the base width is approximately taken equal to 0 6 h to 0 7 h where h is the overall height of the wall. Cantilever retaining walls are constructed of reinforced concrete. Counter fort buttressed retaining wall.

The counterfort retaining wall is a type of retaining wall with counterforts attached to the inside face of the wall to further resist lateral thrust and materials used for retaining walls are treated lumber concrete block systems stone brick and poured concrete.
