Where do we use Counterfort retaining wall?

Counterfort Retaining Walls

• The counterforts tie the slab and base together, and the purpose of them is to reduce the shear forces and bending moments imposed on the wall by the soil.
• Can be precast or formed on site.
• Counterfort retaining walls are more economical than cantilever walls for heights above 25 ft.

What is the strongest type of retaining wall?

Concrete and Masonry Retaining Walls Poured concrete is the strongest and most durable choice for retaining walls. It may also be carved and formed to look like mortared stone depending on your taste.

Under what circumstances Counterfort retaining wall is preferred?

Counterforts are used for high walls with height greater than 8 to 12 m. They are also used in situations where there is high lateral pressure, i.e. where the backfill soils are heavily surcharged. The counterforts help to reduce bending moment and shear forces induced by soil pressure to the retaining wall.

What is the difference between Counterfort and buttress retaining wall?

Type # 5. When the triangular beams are placed on the front side of the retaining wall, instead of on the backfill side under certain situations, the retaining wall is known as buttressed retaining wall, and the triangular beams are known as buttresses, instead of counterforts.

What does Counterfort mean?

buttress
Definition of counterfort : a buttress built against or integral with a wall (as a retaining wall or dam) but on the back or thrust-receiving side.

What is the longest lasting retaining wall?

SRW’s are often the choice of Landscape and Hardscape contractors. Strength – One of the strongest, longest lasting types of retaining walls on the market.

What is Counterfort wall?

A counterfort retaining wall is a cantilever wall with counterforts, or buttresses, attached to the inside face of the wall to further resist lateral thrust. Some common materials used for retaining walls are treated lumber, concrete block systems, poured concrete, stone, and brick.

What is buttress retaining wall?

Buttress wall is a type of the retaining wall. It is similar to the counter fort retaining wall, but the difference is that it is provided on the opposite side of the retained material. The stem of the buttress wall represents the vertical slab in the structure to support the retaining material.

What is a counterfort retaining wall?

A counterfort retaining wall is a form of retaining wall which utilizes an additional support at the back to help hold up the face. Counterfort walls are particularly useful when there are slopes or large overhangs in front of them, because they can use gravity and their extra support to keep from collapsing due to the weight in front.

What are the different types of retaining walls?

Three main types of retaining walls: 1. Gravity retaining wall (depends on its weight for resisting lateral earth force because it have a large weigh) 2. Semi-Gravity retaining wall (reduce the dimensions of the gravity retaining wall by using some reinforcement).

What are the parts of counterfort wall?

The stem of the counterfort wall can be analog to the two-way slab with three fixed ends as well as a free end, which transfers its load at the base of the stem in form of bending moments and then transfers to the base slab. 2) Base slab: The base slab is the footing of the counterfort wall which supports the stem and counterforts.

What is asdip retaining wall design?

ASDIP RETAIN is a structural engineering software for the design of retaining walls. It includes the design of counterfort retaining walls based on the IBC / ACI 318 provisions. This document is a step-by-step design example of a typical counterfort retaining wall using ASDIP RETAIN.
