Quality Inspector

Kaka

Calculate the approximate steel weight for an RCC beam based on volume and steel percentage.

📐 Formula & Method

Calculated using the standard density of steel (7850 kg/m³) and the volume of the structural member.

Weight (kg) = Volume × % × 78.5

📋 Worked Example

For 4m × 0.23m × 0.45m beam at 2% steel:
• Volume = 0.414 m³
• Weight = 0.414 × 0.02 × 7850 ≈ 65 kg

❓ Frequently Asked Questions

What is the percentage of steel in a beam?

For common residential buildings, it ranges from 1% to 2% of the concrete volume.
