Classification of. Retaining walls. • Gravity wall-Masonry or Plain concrete. • Cantilever retaining wall-RCC. (Inverted T and L). • Counterfort retaining wall- RCC. Types of reinforced concrete retaining walls are cantilever retaining walls and counterfort retaining walls. Functions and parts of these retaining walls. In this type of retaining wall, counterforts (cantilevers) are provided on the earth side between wall and footing to support the wall, which essentially spans as a.

Monte Carlo method Search for additional papers on this topic. Design of Isolated Column Footing. Reliability—based design applied to retaining.
Depending upon the height H of the wall the top width of stem can vary between mm to mm. The lateral pressure exerted by the submerged retainig is considered to comprise of the following two components. This is shown in pressure diagram in Fig. Wall retaining partly submerged backfill.
Based on these dimensions the wall is checked for stability checked for overturning, sliding counferfort maximum pressure at toe and in case the stability requirements are satisfied, structural design of different wall components is taken up.
This type of wall with a key is shown in Fig. The pressure thus developed is termed as soil earth pressure.
Four Common Types of Rigid, Monolithic Concrete Retaining Walls
This type of wall proves to be economical for moderate heights say 6 counterfoet 7m. It is also assumed that the retaining wall is allowed to move away from the soil by sufficient amount so that the soil expands and evokes full shearing resistance and attains state of plastic equilibrium. References Publications referenced by this paper. Let the intensity of surcharge load per unit area be w.
Counterfort Retaining Walls When the height of the retaining wall to be provided exceeds 6 to 7m, counterfort retaining wall prove to be economical. Structural Reliability Analysis and Design. Probability, reliability and statistical methods in engineering de-sign.
It may also be defined as a wall provided to maintain ground at two different levels. Cantilever Retaining Walls The material retained by the wall is generally known as backfill. This constant factor of safety may not be able to counteerfort the uncertainties retaibing with the random variables.

Skip to search form Skip to main content. The pressure distribution is triangular. Journal of Geotechnical and Geoenvironmental…. These walls are constructed in brick masonry, stone masonry or plain cement concrete and it is shown in Fig. The more the height of the wall, the closer should be the spacing of counterforts.
The intensity of lateral pressure at the base of the wall in such a case is given by.
Commonly adopted proportions for wall components are as under: The sliding retxining is resisted by retsining frictional resistance between the base of the wall and the soil underneath. Design of RCC footing for Wall. It is necessary to determine, the pressure exerted by the soil in designing a retaining wall. Showing of 32 references. In this type of wall the base slab as well as the stem of the wall span horizontally as continuous slabs between vertical brackets known as counterforts as shown in Fig.
In this case wall has only two components i. The stability of the wall is partially provided by the weight of earth on the heel. The size of the wall is so kept that there is no tensile stress developed at any section of the wall under any condition of loading. The base width b of the retaining wall vary between 0.
The lateral wal imposed by this load does not vary with the height and is uniform. Design of Lintel with Sunshade.
