FIG. 3.7 ECCENTRIC LOADING.
is equivalent to (i) a centrally placed load W and (ii) bending moment M = W . e.
Due to these two, a trapezoidal soil pressure diagram, having pressure intensities q1 and q2 will result.
1 should not exceed the safe bearing pressure for the soil. Also in order that the footing may remain in contact with soil, q2 should be positive (i.e. no tension should be developed). In the extreme case, q2 = 0, when e = B/6. This gives the maximum value of eccentricity. In that case
