Reinforcement Counterfort Retaining Wall Design
Counterfort retaining wall rcc.
Reinforcement counterfort retaining wall design. The toe is the other part of the base. The loads that are of primary concern are the lateral earth pressures induced by the retained soil. Earthquake seismic design 7. Soil bearing and stability 8.
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. Thickness of toe slab buttress not provided 8 of height of wall. Pier and pile foundations 11. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider.
Forces on retaining walls 6. 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. The design of a retaining wall must account for all applied loads. Soil mechanics simplified 4.
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. The base is also divided into two parts the heel and toe. Design example cantilever retaining wall. Design procedure overview 3.
Cantilever retaining walls are constructed of reinforced concrete. Also check for shear at the junction. Counterfort walls are cantilever walls strengthened with counter forts monolithic with the back of the wall slab and base slab. The counter forts act as tension stiffeners and connect the wall slab and the base to reduce the bending and shearing stresses.
The main reinforcement is provided horizontally along the length of the wall. Designing the cantilever wall stem 9. However retaining walls can also be constructed for aesthetic landscaping purposes. Classification of retaining walls.
Under normal conditions the lateral earth pressure is at rest condition. Provide the distribution steel. In no case thickness of any component be less than 300mm. The ties are provided horizontally for the full value of reaction to prevent slab separating from counterforts.
Building codes and retaining walls 5. They consist of a relatively thin stem and a base slab. Thickness of counterfort 6 of height of wall. The heel is the part of the base under the backfill.
Counter fort buttressed retaining wall. This excel sheet introduces design of counterfort retaining wall according. Design of counterfort retaining wall. Preliminary proportioning of counterfort retaining wall.
Counterfort retaining walls 12.
