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 = 706,141 cmâÃÂô, the strong-axis flexural stiffness is suitable for preliminary sizing of beams and beam-columns.
At 1008 mm deep and 349 kg/m, this is a heavy section for primary framing — transfer beams, long-span roof girders, and major bridge stringers.

| Deflection | ÃÂà= 5wLâÃÂô/(384EIx) | Use Ix = 706,141 cmâÃÂô |
| Torsion | St. Venant = GJ/L | J = 1,575 cmâÃÂô |

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: School classroom beam — hem1000
Scenario: School building — tighter deflection limit for suspended ceiling integrity. Simply supported I-section, 17.1 m span, 2.4 m tributary width. Service loads: 3.5 kPa dead + 3.0 kPa live (15.6 kN/m total).
Given:
- Span L = 17136 mm (17.1 m)
- Total service load w = 15.6 kN/m
- Live load portion w_L = 7.2 kN/m
- Section hem1000: Ix = 7061.4 ÃÂà10âÃÂö mmâÃÂô, Sx = 14,011,000 mmÃÂó, Zx = 16,215,000 mmÃÂó
- Steel: fy = 355 MPa, E = 210,000 MPa
- Design moment resistance: ÃÂÃÂMn = 0.9 ÃÂàZx ÃÂàfy = 5,756 kNÃÂ÷m
Step 1 — Live load deflection:
ÃÂÃÂ_LL = 5 w_L LâÃÂô / (384 E Ix)
ÃÂÃÂ_LL = 5 ÃÂà7.2 ÃÂà(17136)âÃÂô / (384 ÃÂà210000 ÃÂà7,061,410,000)
ÃÂÃÂ_LL = 5.5 mm
Step 2 — Deflection limit (L/360):
ÃÂÃÂ_limit = L / 360 = 17136 / 360 = 47.6 mm
Step 3 — Dead + live deflection:
ÃÂÃÂ_total = 11.8 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 = 5,756 kNÃÂ÷m. Also confirm shear resistance and bearing details at the supports.
