This paper presents the results of an experimental investigation of the in-line and lift forces acting on an oscillating column with circular footing. Forced surging tests were carried out using a column with circular footing of which ratio of diameter was varied from 1.25 to 2.5. The in-line and lift force have been measured concerning both the whole model and the parts of column and footing. The drag coefficients, inertia coefficients, coefficients of root-mean-square values of the in-line force and lift force coefficients in the range of Keulegan Carpenter number from 5 to 30 have been obtained. Those results have been compared with that of a straight finite length circular cylinder.
