Estimate linear loads on structural beams.

📐 Formula & Method

Self Weight = W × D × 25. Wall Weight = H × T × 20 (assuming brick density 20 kN/m³).

Self Weight = (W×D/10⁶) × 25

📋 Worked Example

230x450mm beam, 3m wall (230mm):
• Beam SW = 0.23 × 0.45 × 25 ≈ 2.59 kN/m
• Wall Load = 3 × 0.23 × 20 ≈ 13.8 kN/m
• Factored ≈ 24.6 kN/m

❓ Frequently Asked Questions

Why factor of 1.5?

In Limit State Design, 1.5 is the standard partial safety factor for loads to account for uncertainties.
