WisDOT Regional staff determines the need for permanent retaining walls on highway projects. A wall number is assigned as per criteria discussed in . of this chapter . The Regional staff prepares a Structures Survey Report SSR that includes a preliminary evaluation of wall type, location, and height including a preliminary layout plan.
Types of Reinforced Concrete Retaining Wall. Counterfort Retaining Wall. When the height of earth to be retaining exceeds 5m, the bending moment developed in the stem, heel and toe slabs are very large which results in large thickness of structural elements and becomes uneconomical. Counterfort retaining wall consists of a stem, toe
Should the "stem wall" provisions of the IRC be applied to full-height basement walls? EDIT: I just looked at the 2009 IRC; an example would be R.1, R.2 .. I'm on a 2006 derivitive, and I believe the wording is different, but you get the idea. Hard to apply the stem wall provisions if I'm not clear on what a stem wall is.
Wall height: Is the difference in grade level on either side of the wall at a specific location. Retaining Wall: A landscaping technique intended to change the contour or grading of the lot. Construction of any Retaining Wall with exposed height greater than 2-0 two feet requires a permit. Retaining Walls with exposed heights of

DESIGN OF COUNTERFORT RETAINING WALL . Preliminary proportioning of counterfort retaining wall: 1. Thickness of heel slab and stem = 5% of Height of wall . 2. Thickness of toe slab buttress not provided = 8% of Height of wall . 3. Thickness of counterfort = 6% of height of wall . 4. In no case thickness of any component be less than 300mm. 5.
RCC RETAINING WALL CANTILEVERTYPE MAX 6.0 MTR HEIGHT INCL COLUMN LOAD IN LINE. Retaining walls are used in the construction of basement below ground level, wing walls of bridge and to retain slopes in hilly terrain roads. Retaining wall can be constructed with masonry as well as reinforced concrete.
Stem Tab for Restrained Retaining Wall. When a Restrained Retaining Wall is defined, the Stem tab will appear as shown below: If Restrained Stem is selected, you may have a lateral support such as an abutting roof, slab-on-grade over backfill, or tiebacks .
Gravity Retaining Wall Heights. Use the chart below to find the maximum height that your retaining wall can be built before reinforcement is required. The gravity wall heights shown do not account for seismic loading. Check with a local engineer for assistance if you are in a seismic area.
RETAINING WALL DESIGN Retaining walls shall be designed to resist the lateral pressure of the retained material determined in Loads applied within a horizontal distance equal to the wall stem height, measured from the back face of the wall, shall be considered as surcharge.
cantilever retaining wall. 1 Design of stem . Unlike the stem of cantilever retaining wall, the stem of counter fort retaining wall acts as a continuous slab supported on counters forts. Due to varying pressure over the height of stern, the stem slab deflects outwards and hence main reinforcement
Proportioning of reinforced concrete retaining wall elements such as stem, base slab, toe slab and heel slab is important to make the design economical. Proportioning involves calculation for the thickness and width of retaining wall components. Base slab of a retaining wall is so proportioned that
T-WALLs design methodology allows for a stem length that varies over the height of the wall. As the courses are stacked, the stems decrease in length and require less select backfill. The robust precast units efficiently provide the stability needed for gravity retaining walls with extreme height and loading.

Stem Tab for Cantilevered Retaining Wall. Stem Tab for Cantilevered Retaining Wall : The term Stem Design Height refers to a height above the top of the footing i.e. above the base of the stem . It is the height above the bottom of the stem where you want the program to compute moments and shears.
SECTION 5 - RETAINING WALLS Part A . General Requirements and Materials . 5.1 The position of the wall stem relative to the footing can be varied to accommodate The economical height of this type wall is generally limited to a maximum height of 20 feet or less. .
PDF Cantilever L-shaped walls are known to be relatively economical as retaining solution. The design starts by proportioning the wall dimensions for which the stability is checked for. A ratio
