Anything that serves to support something; a prop. 1. As a verb buttress is to support something physically with, or as if with, a prop or buttress. %���� 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. To support something physically with, or as if with, a prop or buttress. In such a case counterforts having trapezoidal section fixed at the base slab are provided at intervals of 1.5 m to 3 m. 4) The base is also divided into two parts, the heel and toe. %PDF-1.4 Use much less concrete than monolithic gravity walls, but require more design and careful construction.

Some common materials used for retaining walls are treated lumber, concrete block … These have some tension reinforcing steel included so as to minimize the thickness of the wall without requiring extensive reinforcement. They are generally economical up to 10 feet in height for cast concrete structures. 2013-02-19T09:53:52Z As nouns the difference between counterfort and buttress is that counterfort is a buttress built against a wall while buttress is (architecture) a brick or stone structure built against another structure to support it. endstream
4. 95 0 obj 4) 3 Earth Pressure (P ) Earth pressure is the pressure exerted by the retaining material on the retaining wall. 2013-02-19T09:53:54Z Buttressed Retaining Walls: 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. 1. Creative Commons Attribution/Share-Alike License; (architecture) A brick or stone structure built against another structure to support it. This pressure tends to deflect the wall outward.
The heel is the part of the base under the backfill. Counterfort retaining walls are more economical than cantilever walls for heights above 25 ft.
Retaining walls are usually built to hold back soil mass. They consist of a relatively thin stem and a base slab. design of counterfort is explianed step by step with simple procedure of design. Counterfort retaining walls are similar to cantilever walls except they have thin vertical concrete webs at regular intervals along the backside of the wall. 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. Buttress wall-RCC. <>
