5.5 Eccentrically loaded spread footings It should be evident that a column can transmit a moment to the footing only if it is rigidly attached. Any footing rotation reduces the moment M applied to the footing with a corresponding 得 change to the far-end moment M;on the column. 志 A sufficiently large rotation can reduce moment to zero(depends on the El/Lc of the column).5.5 Eccentrically loaded spread footings ▪ It should be evident that a column can transmit a moment to the footing only if it is rigidly attached. ▪ Any footing rotation reduces the moment Mf applied to the footing with a corresponding change to the far-end moment Mf ’ on the column. ▪ A sufficiently large rotation can reduce moment to zero (depends on the EIc /Lc of the column)
