The cutting length of the diamond stirrup is done by using simple and easy formula. The stirrups or commonly called ties in the column is used in a column to avoid the lateral deformation of the reinforcement when we are pouring the concrete in columns.
The stirrups or Ties is also used in the column to hold the longitudinal reinforcement in its position when the column is in under construction. The longitudinal bars in the column may change their position or alignment when we pour concrete and use a vibrator.
Let’s solve this example for your better understanding.
Suppose we are using a Diamond stirrup in a column and column having a Length 550 mm and having a Width 450 mm (X-section). The clear cover in the column will be 40 mm and the stirrup bar is going to use is 10 mm.
1. Calculate the cutting length of the diamond stirrup?
2. Also calculate its weight?
Length of column = 550 mm.
Width of column = 450 mm.
Clear cover = 40 mm.
Stirrup bar diameter = 10 mm.
length of the stirrup = ?
Weight of the stirrup = ?
The calculation of the diamond stirrup is to be done on 2 steps. In first step we calculate the Hypotenuses length of the right angle by using Pythagoras theorem. In second step we put these values in our formula to get the final result.
