The formula for direct calculation the dimension of footing base is presented through theoretical　analysis.The calculation can be completed once according to known condition.The relative formula of unit stress ratio, eccentrical degree and the length to breadth ratio of footing are inferred. So the base eccentrical degree and ratio of length to breadth can be controlled applicably according to known　condition.
Keywords: eccentrical compression;  column;  footing base;  dimension; unit stress ratio; length-breadth ratio
