Rcc Retaining Wall Design Reinforcement Details
Functions and parts of these retaining walls are discussed.
Rcc retaining wall design reinforcement details. Design is similar to a rc column breadth equal to thickness of wall and depth equal to 1m. In this example the structural design of the three retaining wall components is performed by hand. Load from slab is transferred as axial load to wall. Rcc wall is.
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. Provide the distribution steel. 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. Soil bearing and stability 8.

Classification of retaining walls backfill backfill gravity rw t shaped rw l shaped rw tile. Retaining wall are generally used to retain earth or other material to maintain unequal levels on two faces.
Coefþcient of friction is 0 4 and the unit weight of reinforced concrete is 24 knm 3 1. Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance. Details of wall mm cf 3 h 7 8. Also check for shear at the junction.
