External diameter,D=25cm.
Internal diameter,d=15cm.
Eccentricity to avoid tension= (D^2+d^2)/8D.
=(25^2+15^2)/(8*25)=4.25cm.

@Brijesh Patel.

Please explain the above mentioned formula.

(25)^2 + (15)^2 /8(25),
850/200 = 4. 25.

To avoid tension in hollow circular column eccentricity (e) should be = D^2 + d^2/8D.
