1. What is Angle Bar Load Capacity?

The Angle Bar Load Capacity calculation determines the maximum load an angle bar can support before yielding, based on its material properties and dimensions. This is crucial for structural engineering and construction applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Yield Strength — Material's yield strength (psi)
• Section Modulus — Geometric property of the cross-section (in³)
• Span — Distance between supports (ft)

Explanation: The equation calculates the maximum bending moment capacity divided by the moment arm (span/2) to determine the maximum point load at midspan.

3. Importance of Load Calculation

Details: Accurate load capacity calculation is essential for structural safety, preventing material failure, and ensuring compliance with building codes and standards.

4. Using the Calculator

Tips: Enter yield strength in psi, section modulus in in³, and span in feet. All values must be positive numbers. Typical steel yield strength is around 36,000 psi for mild steel.

5. Frequently Asked Questions (FAQ)

Q1: What is section modulus for angle bars?
A: Section modulus depends on angle bar dimensions (e.g., L2×2×1/4 has Z≈0.17 in³). Consult engineering tables for specific values.

Q2: Does this account for safety factors?
A: No, this calculates theoretical capacity. Always apply appropriate safety factors per relevant design codes.

Q3: Is this for point load or distributed load?
A: This calculates maximum point load at midspan. For uniform loads, different calculations apply.

Q4: What about deflection limits?
A: This calculates strength capacity only. Deflection should be checked separately for serviceability.

Q5: Can this be used for other shapes?
A: The formula is general but section modulus values differ for other shapes (I-beams, channels, etc.).
