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 = 7,865 cmâÃÂô, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.
At 220 mm deep, this is a mid-range section for secondary beams, roof purlins, and bracing in standard framing.
Key Design Checks (EN 1993)
| Check | Formula | This Section |
|---|---|---|
| Plastic moment | Mp = Zx ÃÂàFy | 285 kNÃÂ÷m |
| Deflection | ÃÂà= 5wLâÃÂô/(384EIx) | Use Ix = 7,865 cmâÃÂô |
| Torsion | St. Venant = GJ/L | J = 65 cmâÃÂô |
| Column buckling | KL/r âÃÂàFcr | r_x = 9.44 cm |
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: Industrial floor beam — heb220
Scenario: Light industrial floor — forklift traffic and storage considerations. Simply supported I-section, 4.6 m span, 3 m tributary width. Service loads: 5.0 kPa dead + 7.5 kPa live (37.5 kN/m total).
Given:
- Span L = 4620 mm (4.6 m)
- Total service load w = 37.5 kN/m
- Live load portion w_L = 22.5 kN/m
- Section heb220: Ix = 78.7 ÃÂà10âÃÂö mmâÃÂô, Sx = 715,000 mmÃÂó, Zx = 802,000 mmÃÂó
- Steel: fy = 355 MPa, E = 210,000 MPa
- Design moment resistance: ÃÂÃÂMn = 0.9 ÃÂàZx ÃÂàfy = 285 kNÃÂ÷m
Step 1 — Live load deflection:
ÃÂÃÂ_LL = 5 w_L LâÃÂô / (384 E Ix)
ÃÂÃÂ_LL = 5 ÃÂà22.5 ÃÂà(4620)âÃÂô / (384 ÃÂà210000 ÃÂà78,650,000)
ÃÂÃÂ_LL = 8.1 mm
Step 2 — Deflection limit (L/250):
ÃÂÃÂ_limit = L / 250 = 4620 / 250 = 18.5 mm
Step 3 — Dead + live deflection:
ÃÂÃÂ_total = 13.5 mm
Step 4 — Design check:
âÃÂàLive 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 ÃÂÃÂMn = 285 kNÃÂ÷m. Also confirm shear resistance and bearing details at the supports.
