Section Profile Summary

This is a standard hot-rolled I-section profile covered by EN 1993. The tabulated section properties are computed from the nominal dimensions per the governing material standard. With Ix = 84,054 cm⁴, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.

At 490 mm deep, this section is common for floor beams, portal frame rafters, and columns in commercial and industrial buildings.

Design Notes

Verification (EN 1993): All designs using this section must be verified by a licensed Professional Engineer. Before finalizing member selection, check beam-column interaction (P-M), lateral-torsional buckling, serviceability deflections, and all connection limit states. See Engineering Disclaimer.

Worked Example: Industrial floor beam — hea500

Scenario: Light industrial floor — forklift traffic and storage considerations. Simply supported I-section, 8.8 m span, 3 m tributary width. Service loads: 5.0 kPa dead + 7.5 kPa live (37.5 kN/m total).

Given:

Step 1 — Live load deflection:

Δ_LL = 5 w_L L⁴ / (384 E Ix)

Δ_LL = 5 × 22.5 × (8820)⁴ / (384 × 210000 × 840,540,000)

Δ_LL = 10.0 mm

Step 2 — Deflection limit (L/250):

Δ_limit = L / 250 = 8820 / 250 = 35.3 mm

Step 3 — Dead + live deflection:

Δ_total = 16.7 mm

Step 4 — Design check:

✓ Live load deflection is within the L/250 limit.

Verify the design moment M*_Ed (from factored loads 1.35G + 1.5Q per EN 1993) does not exceed φMn = 1,354 kN·m. Also confirm shear resistance and bearing details at the supports.
