This construction video tutorial will teach you how to
estimate the steel quantity in column footing with bar bending schedule.
Column Footing stands for an independent footing or
foundation under a column or either equivalent member for delivering the
concentrated load by means of uniformly loads to the soil underneath in order
that the bearing capacity of the soil is not surpassed and differential
settling does not take place. The footing may come in square, rectangular or
circular in plan.
The footing may be constructed with brick masonry, stone,
R.C.C., steel grill-age etc on the basis of the load to be transferred as well
as the bearing capacity of soil. As a result of low bending strength, the
footings built with brick, stone or plain concrete need extensive depth to bear
heavy loads safely.
The depth of plain concrete footing is minimized
significantly with the arrangement of reinforcements at its base to withstand
tensile stresses. R.C.C. column footings may com in circular, rectangular or
square in plan. The footing is reinforced both-ways using mild steel ribbed
bars which are arranged at exact angles to one another at similar distances
apart.
