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 = 15,524 cmâÃÂô, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.
At 360 mm deep, this section is common for floor beams, portal frame rafters, and columns in commercial and industrial buildings.
Key Design Checks (EN 1993)

|---|---|---|
| Plastic moment | Mp = Zx ÃÂàFy | 346 kNÃÂ÷m |
| Deflection | ÃÂà= 5wLâÃÂô/(384EIx) | Use Ix = 15,524 cmâÃÂô |
| Torsion | St. Venant = GJ/L | J = 29 cmâÃÂô |
| Column buckling | KL/r âÃÂàFcr | r_x = 14.9 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: Hospital ward beam — ipe360
Scenario: Hospital ward — strict deflection limits for medical equipment and services. Simply supported I-section, 7.2 m span, 2.1 m tributary width. Service loads: 4.0 kPa dead + 3.0 kPa live (14.7 kN/m total).
Given:
- Span L = 7200 mm (7.2 m)
- Total service load w = 14.7 kN/m
- Live load portion w_L = 6.3 kN/m
- Section ipe360: Ix = 155.2 ÃÂà10âÃÂö mmâÃÂô, Sx = 862,000 mmÃÂó, Zx = 974,000 mmÃÂó
- Steel: fy = 355 MPa, E = 210,000 MPa
- Design moment resistance: ÃÂÃÂMn = 0.9 ÃÂàZx ÃÂàfy = 346 kNÃÂ÷m
Step 1 — Live load deflection:
ÃÂÃÂ_LL = 5 w_L LâÃÂô / (384 E Ix)
ÃÂÃÂ_LL = 5 ÃÂà6.3 ÃÂà(7200)âÃÂô / (384 ÃÂà210000 ÃÂà155,240,000)
ÃÂÃÂ_LL = 6.8 mm
Step 2 — Deflection limit (L/360):
ÃÂÃÂ_limit = L / 360 = 7200 / 360 = 20.0 mm
Step 3 — Dead + live deflection:
ÃÂÃÂ_total = 15.8 mm
Step 4 — Design check:
âÃÂàLive load deflection is within the L/360 limit.
Verify the design moment M*_Ed (from factored loads 1.35G + 1.5Q per EN 1993) does not exceed ÃÂÃÂMn = 346 kNÃÂ÷m. Also confirm shear resistance and bearing details at the supports.
