1. What is the Thickness Calculation?

The thickness calculation determines the required thickness of polycarbonate panels based on the expected load, span length, material strength, and panel width. This ensures structural integrity and safety.

2. How Does the Calculator Work?

The calculator uses the thickness formula:

Where:

• \( Load \) — Distributed load (kg/m²)
• \( Span \) — Distance between supports (m)
• \( Allowable\ Stress \) — Material's maximum stress capacity (MPa)
• \( Width \) — Panel width (m)

Explanation: The equation calculates the minimum thickness needed to withstand the given load without exceeding the material's stress limits.

3. Importance of Thickness Calculation

Details: Proper thickness calculation ensures polycarbonate panels can support expected loads (snow, wind, etc.) without excessive deflection or failure, while optimizing material usage.

4. Using the Calculator

Tips: Enter all values in the specified units. Typical allowable stress for polycarbonate ranges from 10-30 MPa depending on grade and safety factors.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical load value for roofing?
A: For residential areas, snow load might be 100-150 kg/m², while wind load depends on location and building height.

Q2: How does span affect thickness?
A: Thickness increases with the square of the span - doubling the span requires 4x the thickness for the same load.

Q3: What safety factors should be considered?
A: The allowable stress should include appropriate safety factors (typically 2-4x) below the material's yield strength.

Q4: Does temperature affect the calculation?
A: Yes, polycarbonate properties change with temperature. Use appropriate stress values for the expected temperature range.

Q5: Can this be used for other materials?
A: The formula is general, but you must use the correct allowable stress for the specific material being calculated.
