Retaining walls are generally used to retain earth or such materials to maintain unequal levels on its two faces. The soil on the back face is at a higher level and is called back fill. Retaining wall is extensively used in the construction of basements below ground level, wing walls of bridge and to retain slopes in hilly terrain roads.
The most common and widely used retaining wall is of cantilever type. Vertical stem resisting earth pressure one side and the slab bends like a cantilever. The thickness of the vertical slab is large at the bottom and decreases towards the top in proportion to the varying soil pressure.
Counter fort retaining walls are used for large heights exceeding 5 mts of earth fill. In counter fort retaining wall the vertical stem is designed as a continuous slab spanning between the counter forts. Counter forts are designed as cantilever beams from the base slab.
The stem of the counter fort retaining wall acts as a continuous slab supported on counter forts. The counter forts take reactions both from the stem as well as the heel slab. Since the active earth pressure on stem acts outwards and net pressure heel slab acts downwards, the counter forts are subjected to tensile stresses along the outer face of the counter forts.

Minimum area of steel is 0.3 percent of gross area of section up to 100mm thick, reduced to 0.2 percent in section up to 450mm thick. For sections above 225mm thick, provide two layers of reinforcement. The percentage of reinforcement in base or floor slab resisting directly on ground must be not less than 0.15% of the concrete section.
The minimum cover to all reinforcement should be not less than 25mm or the diameter of the bar whichever is greater.
For small capacity tanks individual footings for columns can be provided. Infact, the type of footing will depend upon the nature of soil and type of staging. In case of low lying areas of low safe bearing capacity with high ground water table, pile footings are provided. In any case of foundation slab, leans mix of 1:4:8, 150mm thick may be provided as leveling course.
If a deformable structure in equilibrium under the action of a system of external forces is subjected to a virtual deformation compatible with its condition of support, the work done by these forces on the displacements associated with the virtual deformation is equal to the work done by the internal stresses on the strains associated with this deformation.
Due to a given system of rolling loads the maximum shear force for every section of the girder can be worked out by placing the loads in appropriate positions. When these are plotted for all the sections of the girder, the diagram that we obtain is the maximum shear force diagram. This diagram yields the ‘design shear’ for each cross section.
