Rcc Retaining Wall Design Reinforcement Details

Soil mechanics simplified 4.

Rcc retaining wall design reinforcement details.

Forces on retaining walls 6. 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. Coefþcient of friction is 0 4 and the unit weight of reinforced concrete is 24 knm 3 1. Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.

Provide enough development length. Design example cantilever retaining wall. Functions and parts of these retaining walls are discussed. Retaining wall are generally used to retain earth or other material to maintain unequal levels on two faces.

This session is not intended to teach concrete design but more of an awareness of why things are the way they are. Earthquake seismic design 7. Types of reinforced concrete retaining walls are cantilever retaining walls and counterfort retaining walls. Design is similar to a rc column breadth equal to thickness of wall and depth equal to 1m.

The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. Counterfort retaining wall rcc buttress wall rcc 3. Let s take a look at these in a little more detail and see what happens if the parameters for a particular design are not met 牜. Determine the factors of safety against sliding and overturning.
