# How to determine the cutting length of circular ties

Construction Software This construction video tutorial presented by the renowned engineer S.L. Khan will teach you how to find out the cutting length of a circular tie with some easy to follows tips.

In this video, the solution is given to the following problem :-

Problem : Find out the cutting length of the column’s tie on the basis of the following dimensions :-

Diameter of circular column = 1 meter

Main bars = 25 mm

Tie = 10 mm

Hook bar tie @8 diameter i.e. 8 times diameter of the tie submitted by designer.

Concrete coverage = 25 mm

Keep in mind that the tie comes as circular in shape in order that the length of the tie should become the circumference of the circle that is πD with the inclusion of hook.

Therefore, to determine the total cutting length of the tie, the following formula will be used :-

πD + 8d

Here, D denotes effective diameter of the column (center to center of the tie)

d denotes diameter of the ties (for hook).

To learn the detail calculation process, go through the following video tutorial.
