1. What is Web Depth Clear of fillets?

Definition: Web Depth Clear of fillets (d_c) is the distance between the starting and end of the web ignoring the fillets at both sides.

Purpose: It's an important measurement in structural engineering for calculating the strength and stability of I-beams and other structural members.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( d_c \) — Web Depth Clear of fillets (meters)
• \( D \) — Depth of Section (meters)
• \( k \) — Distance from Flange to Web Fillet (meters)

Explanation: The total section depth minus twice the fillet distance gives the clear web depth between fillets.

3. Importance of Web Depth Calculation

Details: Accurate web depth calculation is crucial for determining shear capacity, buckling resistance, and overall structural integrity of beams.

4. Using the Calculator

Tips: Enter the depth of section (D) and distance from flange to web fillet (k) in meters. Both values must be > 0. The ±5% indicates typical tolerance ranges.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for web depth?
A: Web depth varies significantly based on beam size, but typically ranges from 50mm to over 1000mm in large structural beams.

Q2: Why do we exclude the fillets in this calculation?
A: Fillets are transition areas and are typically not considered in web depth calculations for structural analysis purposes.

Q3: How do I measure the distance from flange to web fillet?
A: This is usually specified in beam tables or can be measured from technical drawings as the distance from the flange's outer face to the web toe.

Q4: Does this calculation apply to all beam types?
A: Primarily for I-beams and similar sections. Different formulas may be needed for box sections or other profiles.

Q5: What's the significance of the ±5% tolerance?
A: This accounts for manufacturing variations and measurement uncertainties in real-world applications.
