Top Chord Length Calculator

Top chord length calculator is a useful tool for construction and engineering projects. For using basic calculator enter truss base ($), truss height ($), into the input fields of the calculator and the by pressing calculate button it will evaluate top chord length in the result field.

Want more detailed advance calculation turn advance mode on enter truss base 1 ($), truss height 1 ($), truss Base 2 ($), truss height 2 ($) as input into the calculator and it will show you combined top chord length in the result.

What Is Top Chord Length

Top Chord Length refers to the length of the upper edge of a truss, which spans from one end of the truss to the other, often forming the hypotenuse of a right triangle.

Formulas

The calculator calculate your input values in two modes basic and advance. Following are formula’s for each mode.

1. Basic Formula

$\text{Top Chord Length} = \sqrt{\left(\frac{\text{Base}}{2}\right)^2 + \text{Height}^2}$

2. Advanced Formula

$\text{Combined Top Chord Length}$

$\text{Combined Top Chord Length} = \sqrt{\left(\frac{\text{Base 1}}{2}\right)^2 + \text{Height 1}^2} + \sqrt{\left(\frac{\text{Base 2}}{2}\right)^2 + \text{Height 2}^2}$

Variables

1. Basic Calculation Variables

• Base: The length of the base of the truss (in inches).
• Height: The height of the truss (in inches).

2. Advanced Calculation Variables

• Base 1: The length of the first base of the truss (in inches).
• Height 1: The height of the first truss (in inches).
• Base 2: The length of the second base of the truss (in inches).
• Height 2: The height of the second truss (in inches).

Calculation Example

1. Basic Calculation Example

Using the basic formula:

$\text{Top Chord Length}$

$\text{Top Chord Length} = \sqrt{\left(\frac{40}{2}\right)^2 + 30^2} = \sqrt{20^2 + 30^2} = \sqrt{400 + 900} = \sqrt{1300} \approx 36.06 \, \text{inches}$

2. Advanced Calculation Example

Using the advanced formula:

$\text{Combined Top Chord Length}$

$\text{Combined Top Chord Length} = \sqrt{\left(\frac{40}{2}\right)^2 + 30^2} + \sqrt{\left(\frac{50}{2}\right)^2 + 40^2}$

Combined Top Chord Length=

$\approx 36.06 + 47.17 = 83.23 \, \text{inches}$
