Rcc Retaining Wall Reinforcement Details
In case of masonry retaining wall the thickness of wall increases with height because masonry resists the lateral pressure by its weight.
Rcc retaining wall reinforcement details. Gravity retaining wall gl1 gl2 retaining walls are usually built to hold back soil mass. Thus it is also called gravity retaining wall. Counterfort retaining wall rcc buttress wall rcc 3. In this video lecture i show you how we construct the retaining wall at sit what type of bar was to be use it is very important to understand so check.
Meanwhile the height of earth to be retaining go beyond 5 meter the bending moment started in the stem heel and toe slabs are very large which gives rise to large thickness of structural elements and turns out to be pricy therefore counterfort type retaining wall is selected for larger heights. M c c 400 mm. Most walls will have window or door openings or both. 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 reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section. 125 retaining walls example 3 16 design of a cantilever retaining wall bs 8 110 the cantilever retaining wall shown below is backþlled with granular material having a unit weight of 19 knm 3 and an internal angle of friction of 30. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. Counterfort retaining wall comprises of a stem toe slab and heel.
Creating a wall opening in a reinforced concrete wall creates extra stress around that opening especially at the corners. A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement. Reinforcement is provided on earth. Reinforcement for wall openings.
Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m. This type of walls has vertical stem monolithic with the base. Provide enough development length. Classification of retaining walls backfill backfill gravity rw.
Also check for shear at the junction. Window and door headers also known as lintels can be subjected to significant bending moment and shear forces depending on several factors.
