1. What is Yield Load for Projection of Base Plate?

Definition: This calculator determines the yield load at which plastic deformation begins in the base plate projection beyond the flange.

Purpose: It helps structural engineers ensure base plates can withstand factored loads without yielding.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Fy = m^2 \times \left( \frac{2 \times Pu}{0.9 \times N \times B \times t^2} \right) \]

Where:

  • \( Fy \) — Yield load (kN)
  • \( m \) — Projection beyond flange (mm)
  • \( Pu \) — Factored load (kN)
  • \( N \) — Length of base plate (mm)
  • \( B \) — Width of base plate (mm)
  • \( t \) — Thickness of base plate (mm)

3. Importance of Yield Load Calculation

Details: Proper calculation ensures structural integrity and prevents premature failure of base plate connections.

4. Using the Calculator

Tips: Enter all dimensions in mm and load in kN. The tolerance field (±%) allows for safety factor adjustments.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical tolerance percentage?
A: ±5% is common, but this may vary based on project specifications and safety requirements.

Q2: How is factored load determined?
A: Factored load is calculated by applying load factors to service loads as specified in building codes.

Q3: What if my base plate has unequal projections?
A: Use the larger projection value for conservative calculations.

Q4: Does this consider material properties?
A: The formula implicitly considers material yield through the factored load approach.

Q5: When would I need a negative tolerance?
A: Negative tolerance might be used for worst-case scenario analysis.
