Commenting on Mr. S. P. Banerjee’s contribution to the discussion, Professor A. L. L. BAKER writes: On page 24, reference 21, it is stated that moments M b and M b + M c are approximately proportional to their corresponding deflections. The closeness of the approximation depends on the degree of similarity of shape of the bending moment diagrams. When the ratio of Y b / M b is greater than Y c / M c which is usual on account of the relative shapes of the M b and M c diagrams, the approximation is on the safe side. Even in special cases, when this is not true, the vagueness of K values for the soil and their distribution, and EI values for beams and their distribution necessitates the use of extreme safe limiting values, which justifies using the above convenient approximation.
