IPE500 IPE — European I-Section Section Properties

IPE500 is a European IPE (I-Section) per EN 10365 (successor to DIN 1025 / EN 10034) hot-rolled structural steel section. Standard European IPE dimensions per EN 10365. Verify against ArcelorMittal / Tata Steel section catalog.

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 = 46,207 cm⁴, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.

At 500 mm deep, this section is common for floor beams, portal frame rafters, and columns in commercial and industrial buildings.

Key Design Checks (EN 1993)

Design Notes

• Compactness: Verify flange and web slenderness against EN 1993 Table B4.1 classification limits for the governing load case (pure compression, pure flexure, or combined).
• Combined loading: For members under simultaneous axial force and bending, use the interaction equations in EN 1993 Section H. The governing equation depends on the ratio of required to available axial strength.
• Connection limit states: Check bolt bearing, tear-out, block shear, and weld strength at all connections. The governing connection limit state often controls the member size selection.

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) — ipe500

Scenario: Flat roof with services — allowance for mechanical units and drainage. Simply supported I-section, 10.5 m span, 3.6 m tributary width. Service loads: 2.0 kPa dead + 1.5 kPa live (12.6 kN/m total).

Given:

• Span L = 10500 mm (10.5 m)
• Total service load w = 12.6 kN/m
• Live load portion w_L = 5.4 kN/m
• Section ipe500: Ix = 462.1 × 10⁶ mm⁴, Sx = 1,848,000 mm³, Zx = 2,107,000 mm³
• Steel: fy = 355 MPa, E = 210,000 MPa
• Design moment resistance: φMn = 0.9 × Zx × fy = 748 kN·m

Step 1 — Live load deflection:

Δ_LL = 5 w_L L⁴ / (384 E Ix)

Δ_LL = 5 × 5.4 × (10500)⁴ / (384 × 210000 × 462,070,000)

Δ_LL = 8.8 mm

Step 2 — Deflection limit (L/250):

Δ_limit = L / 250 = 10500 / 250 = 42.0 mm

Step 3 — Dead + live deflection:

Δ_total = 20.6 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 = 748 kN·m. Also confirm shear resistance and bearing details at the supports.
