Functions and parts of these retaining walls are discussed.

Rcc retaining wall design reinforcement details.

Determine the factors of safety against sliding and overturning. This session is not intended to teach concrete design but more of an awareness of why things are the way they are. Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. 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.

The base is divided into two parts the heel and toe. Calculate ground bearing pressures. Counterfort retaining wall comprises of a stem toe slab and heel. 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.

Design is similar to a rc column breadth equal to thickness of wall and depth equal to 1m. Classification of retaining walls backfill backfill gravity rw t shaped rw l shaped rw tile. M h1 7 m h 8 25 m. Earthquake seismic design 7.

Design the wall and base reinforcement assuming fcu 35 knm 2 f y 500 knm 2 and the cover to reinforcement in the wall and base are respectively 35. Retaining wall are generally used to retain earth or other material to maintain unequal levels on two faces. Cantilever retaining wall rcc inverted t and l. 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.
