Haunch bar length calculation
Haunch Bar Cutting Length Calculation for estimation of reinforcements bar needs in the work is the most essential part because without estimation you have no idea about how many quantities required for haunch bar cutting length in building project construction.
How to Find Haunch Bar Length for Cutting
Here Civil Experience take an example of how to calculate haunch bar for a better understanding of how to calculate cutting length of haunch bar.
The example gives you the flow of calculation methods because every site requires a different kind of design due to different kind of soil, environmental conditions, groundwater level, temperature etc.
So here we considered 3 steps for Haunch Bar Cutting Length Calculation.
Step consideration in Haunch Bar Cutting Length Calculation

Step 1: Diagonal length Haunch Bar
The diagonal length of the haunch bar
For diagonal calculation, we use Pythagoras theorem
Pythagoras theorem is diagonal length is equal to the square root of the sum of both side square sum
AC^2 = AB^2 + BC^2
Where B has 90 angels
In our Design
Diagonal length = Square root ( square of ( 380 + 75 + 50) ) + ( square of ( 380 + 75 + 50 ) )
Diagonal length = 714 mm
Here we cal take 715 mm for easy simple calculation
380+75+50 is the total vertical and also horizontal length in your case may be is different so be care full
Step 2: Supporting length of Haunch Bar
Now we adding value which given after diagonal length in Haunch Bar Cutting Length Calculation
Here additional value is 300 mm for the upper side and 200 mm lower side
Step 3: Hook length of Haunch Bar
The Third Step is adding hook length in Haunch Bar Cutting Length Calculation
Here is 50 mm for both ends
Final total length of haunch bar = 50 + 300 + 715 + 200 + 50
Total length of haunch bar = 1315 mm
Note: is depend on your design requirement of the structure may be is some case is not provided when not provided then ignore it or assume its value zero
