Retaining wall are generally used to retain earth or other material to maintain unequal levels on two faces. Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. When depth is large it is called rc wall. This session is not intended to teach concrete design but more of an awareness of why things are the way they are.

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. Determine the factors of safety against sliding and overturning. Reinforced concrete wall design basics mike o shea p e. 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.
