What is a Beam Length?

Usually, beam length has just been made to generally refer to the total distance that a structural beam will extend in any particular construction. Beams are horizontal construction elements, spanning an open space and designed to carry loads such as floors or roofs.

How to Use the Calculator

Using the calculator is straightforward. Follow these steps:

1. Enter the Effective Depth (mm):

Input the effective depth of the beam in millimeters into the “Effective Depth (mm)” field.

2. Enter the Diameter of the Bar (mm):

Input the diameter of the reinforcing bar in millimeters into the “Diameter of the Bar (mm)” field.

3. Enter the Clear Cover Size (mm):

Input the clear cover size in millimeters into the “Clear Cover Size (mm)” field.

Example:

  • Effective Depth: 400 mm
  • Diameter of the Bar: 16 mm
  • Clear Cover Size: 25 mm

How to Calculate Beam Length

The formula to calculate the beam length is as follows:

BEL=ED+D2+CS\text{BEL} = \text{ED} + \frac{\text{D}}{2} + \text{CS}

Variables:

Variable Description
BEL Beam Length (in)
ED Effective Depth (mm)
D Diameter of the Bar (mm)
CS Clear Cover Size (mm)

Calculation Steps:

  1. Measure the effective depth (ED) in millimeters.
  2. Measure the diameter of the bar (D) in millimeters.
  3. Measure the clear cover size (CS) in millimeters.
  4. Use the formula: BEL = ED + (D/2) + CS.

Example Calculation:

1. Inputs:

    • Effective Depth (ED): 400 mm
    • Diameter of the Bar (D): 16 mm
    • Clear Cover Size (CS): 25 mm

2. Calculation:

    • First, measure the effective depth: 400 mm.
    • Next, measure the diameter of the bar and divide by 2: 16 mm / 2 = 8 mm.
    • Then, measure the clear cover size: 25 mm.
    • Finally, add these values together: 400 mm + 8 mm + 25 mm = 433 mm.

3. Result:

The beam length needed is 433 mm.

Inputs Examples

Following are the two random input values examples that can help you how you enter the your values and get your result.

1. Basic Example:

Input Fields Values
Effective Depth (mm) 400
Diameter of the Bar (mm) 16
