What is the ring size of column 600x400 (8mm dia ring) ?
Answer Posted / abhinav
600*400 column size
Cover 40mm
So 2*(520+320 )= 1680
+ Hook length = 10d*2 = 160mm
- bend deduction= 3*2d+ 2*3d = 12d = 96mm
- bar dia (8mm)= 8mm
So 1680+160-96-8 = 1840- 104= 1736mm

) Design a gussetted base for a column section consisting of one sc 250 with two cover plates 300 x 25 mm carrying an axial load of 2500 KN. The S.B.C. of soil is 250 KN/m2 and the permissible bearing pressure on concrete is 4000 KN.
In foundation design, while we do the base pressure check, we normally check if the attained pressure value is less than the GROSS BEARING CAPACITY of the soil which is the sum of net bearing capacity of soil and the overburden pressure. Actually, the overburden pressure acts against the net bearing capacity of the soil and I feel that we are actually increasing the bearing capacity value and doing the check. I feel that this is NOT right. Please clarify on this.
