Reinforcement Rcc Retaining Wall Design

Determine the factors of safety against sliding and overturning.

Reinforcement rcc retaining wall design.

Soil mechanics simplified 4. The primary difference between them is their height. In instance of masonry retaining wall the thickness of wall enhances with height for the reason that masonry opposes the lateral pressure by its mass. Calculate ground bearing pressures.

Coefþcient of friction is 0 4 and the unit weight of reinforced concrete is 24 knm 3 1. Earthquake seismic design 7. A gravity wall h 3m masonry or stone b cantilever wall h 3m and h 6m c counterfort wall h 8m d buttress wall transverse stem support provided on front side e e bridge abutment additional horizontal restraint from bridge deck a gravity wall h 3m masonry or stone. Although retaining wall was the subject of the last post their design was not covered.

This session is not intended to teach concrete design but more of an awareness of why things are the way they are american concrete institute building code requirements for structural concrete aci 318 which is referenced in nrcs. Also check for shear at the junction. Retaining wall retains earth when level difference exists between two surfaces. There are three different forms of this type of wall all of which are designed to resist overturning and sliding failure.

Design procedure overview 3. Cantilever retaining wall rcc inverted t and l. Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance. As a result it is also known as gravity retaining wall.

Provide the distribution steel. Provide enough development length. 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. Reinforced concrete wall design basics mike o shea p e.

Retaining wall can be built with masonry along with reinforced concrete. 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. Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.

Design example cantilever retaining wall. 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. This post will focus on the design of reinforced concrete cantilever walls. Soil bearing and stability 8.
