This is a simplified mono truss analysis. For critical structures, consult a professional engineer.

When it comes to designing safe and efficient structures, trusses play a critical role in supporting roofs, bridges, and other frameworks. However, calculating forces, deflection, and safety ratios for a truss can be time-consuming and complex—especially if you’re doing it manually. The Mono Truss Calculator is a powerful tool designed to simplify these calculations. With just a few inputs, this calculator provides a quick and reliable estimate of your truss’s performance.

Whether you are a civil engineer, architect, student, or DIY enthusiast, this tool helps you analyze mono trusses efficiently while saving time and reducing calculation errors.

What is the Mono Truss Calculator?

The Mono Truss Calculator is an online tool that estimates critical parameters of a single-pitched (mono) truss. Using simple inputs such as truss span, height, load, material properties, and section area, it provides:

  • Maximum top chord (compression) and bottom chord (tension) forces
  • Maximum diagonal and vertical forces
  • Estimated maximum deflection
  • Safety ratio for quick assessment

This tool is designed for preliminary analysis and quick estimates. For final structural design, consulting a licensed engineer is recommended.

How to Use the Mono Truss Calculator: Step-by-Step

Using the Mono Truss Calculator is straightforward. Follow these steps:

Step 1: Enter Truss Dimensions

  • Truss Span (L): Enter the horizontal length of the truss in meters.
  • Truss Height (h): Enter the vertical height of the truss in meters.

Step 2: Enter Load Information

  • Uniform Load (w): Input the load applied on the top chord in kN/m.

Step 3: Specify Truss Details

  • Number of Panels (nodes): Enter the number of panels or segments in the truss (minimum 2).

Step 4: Enter Material Properties

  • Young’s Modulus (E): Input the material’s Young’s modulus in MPa (default is 200,000 MPa for steel).
  • Section Area (A): Provide the cross-sectional area of the truss members in mm².

Step 5: Calculate and View Results

Click the “Calculate” button. The calculator will simulate the analysis and display:

  • Maximum top chord force
  • Maximum bottom chord force
  • Maximum diagonal/vertical force
  • Estimated deflection
  • Safety ratio

A tip is also displayed for guidance: “For actual design, check local codes and real truss geometry. This tool uses simplifications for quick estimates only.”

Step 6: Copy or Share Results

The tool allows you to copy the results to your clipboard or share them directly via available sharing options.

Practical Example

Suppose you have a mono truss with the following parameters:

  • Span: 10 m
  • Height: 2 m
  • Uniform load: 5 kN/m
  • Number of panels: 4
  • Young’s Modulus: 200,000 MPa
  • Section area: 500 mm²

Using the Mono Truss Calculator:

  1. Enter the above values into the corresponding fields.
  2. Click Calculate.
  3. The calculator will display:
  • Maximum Top Chord Force: ~62.5 kN (compression)
  • Maximum Bottom Chord Force: ~62.5 kN (tension)
  • Maximum Diagonal Force: ~6.25 kN
  • Estimated Deflection: ~3.2 mm
  • Safety Ratio: 2.0 (safe)

This quick result helps you decide if the truss size and material are adequate for the intended load.
