Combined Footings

Combined footings are constructed in a way that the centre of gravity of the supporting area coincides the line of centre of gravity of the two column loads. These are usually in the form of rectangular or trapezodial in shape. Rectangular shape is adopted where loading condition is such that either the two columns are equally loaded or the interior column carries greater load. On the other hand, in case of trapezodial footing, no such condition is applicable.
