In this article, we will learn about How to calculate Cutting length of Rectangular Stirrup? | Cutting length of rectangular stirrup means its length and weight calculation is very easy and simple. The bar bending schedule is very important in every construction work. Without known the proper length and proper quantity of the stirrups, it is very difficult to do the construction work properly.
Cutting length of the stirrup is very important because in every beam we use stirrups and the mean is the most important member in the construction buildings.
In this article, we are going to discuss the rectangular stirrup cutting length calculation in detail. Before going for calculation lets clear the following basic concepts.
The cutting length of a rectangular stirrup is calculated using the following formula:
Cutting length = Perimeter + Hook length - Bend length
- Perimeter: The perimeter of the stirrup is the distance around the stirrup, measured outside the bends.
- Hook length: The hook length is the length of the hook on each end of the stirrup. The hook length is typically 9 times the diameter of the stirrup bar.
- Bend length: The bend length is the length of the bend at each corner of the stirrup. The bend length is typically 2 times the diameter of the stirrup bar.
For example, if the stirrup has a diameter of 10 mm, the perimeter is 40 mm, the hook length is 90 mm, and the bend length is 20 mm. The cutting length would be:
Cutting length = 40 mm + 90 mm - 20 mm = 50 mm
It is important to note that the cutting length must be at least 12 times the diameter of the stirrup bar. This is to ensure that the stirrup is strong enough to resist the forces that it will be subjected to.
Here are some additional tips for calculating the cutting length of a rectangular stirrup:
- Always use the actual diameter of the stirrup bar when calculating the cutting length. Do not use the nominal diameter.
- The hook length and bend length are typically specified in the structural design drawings. If they are not specified, you can consult the applicable building code or engineering standards.
- When cutting the stirrups, it is important to use a sharp saw to prevent the stirrup bars from becoming damaged.
- It is also important to make sure that the stirrups are cut at a straight angle. This will help to ensure that the stirrups are properly aligned when they are installed.
What is the bar bending schedule?
Bar bending is defined as The schedule is provided at the site. In which the list of reinforcement is provided in detail means the length of the different section their required quantity etc. The bar bending schedule is very for every construction work because without this schedule the construction work is not proceeding properly.
For your better understanding let’s take this example.
