Reinforcement Counterfort Retaining Wall Design

Cantilever retaining walls are constructed of reinforced concrete.

Reinforcement counterfort retaining wall design.

Thickness of toe slab buttress not provided 8 of height of wall. Earthquake seismic design 7. Design example cantilever retaining wall. The main reinforcement is provided horizontally along the length of the wall.

The design of a retaining wall must account for all applied loads. Also check for shear at the junction. However retaining walls can also be constructed for aesthetic landscaping purposes. Building codes and retaining walls 5.

The counter forts act as tension stiffeners and connect the wall slab and the base to reduce the bending and shearing stresses. The heel is the part of the base under the backfill. Design procedure overview 3. The ties are provided horizontally for the full value of reaction to prevent slab separating from counterforts.

Soil bearing and stability 8. In no case thickness of any component be less than 300mm. Counterfort walls are cantilever walls strengthened with counter forts monolithic with the back of the wall slab and base slab. Classification of retaining walls.

Preliminary proportioning of counterfort retaining wall. Design of counterfort retaining wall. 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.

Counterfort retaining walls 12. 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. Thickness of heel slab and stem 5 of height of wall. 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.

Soil mechanics simplified 4. Counterfort retaining wall rcc. Designing the cantilever wall stem 9. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.

Provide the distribution steel. Provide enough development length. Thickness of counterfort 6 of height of wall. Counter fort buttressed retaining wall.

The base is also divided into two parts the heel and toe. 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. Under normal conditions the lateral earth pressure is at rest condition. The loads that are of primary concern are the lateral earth pressures induced by the retained soil.

This excel sheet introduces design of counterfort retaining wall according.
