Minimum Concrete Retaining Wall Thickness

For more on designing bearing walls refer to chapter 11 of aci 318 19.

Minimum concrete retaining wall thickness.

4 2 exterior basement wall and foundation wall. Bed joints of the starting course over the concrete foundation may be between 1 4 and 3 4. Thus it appears that in the example you provided the minimum wall thickness is 6 inches. Aci 530 1 05 section 3 3b nospecialinspectionisrequiredforretain ingwallsupto6feetinheight.

Minimum thickness of walls 4 1 bearing walls. Enter length and height in feet and thickness in inches. As soon as you go higher or have greater depths of soil pushing against the wall you need to increase the thickness to 10 inches. Enter the height feet.

1 2 3 4 5 6 6. Top thickness 18 in. All head and bed joints shall be 3 8 thick. Bottom retaining wall loads the following figure shows all the loads applied to the cantilever retaining wall where.

In general poured concrete basement walls that are 8 feet tall or less and have no more than 7 feet of soil pressing against them from the outside function well at a thickness of 8 inches. Section 11 3 1 1 states that the minimum thickness shall be based on the shorter of either the unsupported wall height or length. Wall stem dimensions wall foundation dimensions width 1 ft strip width 1 ft strip height 13 5 ft length 9 75 ft thickness 8 in. Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well.

Enter the thickness inches. Ubc specified minimum thickness of exterior basement wall and foundation wall to be 191mm. These consists of a concrete or masonry wall of uniform thickness vertical wall reinforcing and transverse footing reinforcing are all designed for the lateral shear and cantilever bending movement plus the vertical weights of the wall footing and earth fills. Ubc recommends minimum thickness of bearing wall to 1 25 supported height or length whichever is shorter or not less than 102mm.

B short retaining walls vertical walls up to about 3m in height are usually built as shown in figure 1 b. V l x h x t.
