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 = 3,671 cm⁴, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.

At 240 mm deep, this is a mid-range section for secondary beams, roof purlins, and bracing in standard framing.

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: Roof beam (flat roof) — ipe240

Scenario: Flat roof with services — allowance for mechanical units and drainage. Simply supported I-section, 5.0 m span, 3.6 m tributary width. Service loads: 2.0 kPa dead + 1.5 kPa live (12.6 kN/m total).

Given:

Step 1 — Live load deflection:

Δ_LL = 5 w_L L⁴ / (384 E Ix)

Δ_LL = 5 × 5.4 × (5040)⁴ / (384 × 210000 × 36,710,000)

Δ_LL = 5.9 mm

Step 2 — Deflection limit (L/250):

Δ_limit = L / 250 = 5040 / 250 = 20.2 mm

Step 3 — Dead + live deflection:

Δ_total = 13.7 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 = 123 kN·m. Also confirm shear resistance and bearing details at the supports.
