Section Profile Summary

A wide flange with parallel flange faces — makes bolted and welded connections straightforward to detail. At Ix = 99,895 cm⁴, the strong-axis stiffness places it in the heavy beam category for preliminary sizing.

At 393.7 mm deep, this section is common for floor beams, portal frame rafters, and columns in commercial and industrial buildings.

Key Design Checks (CSA S16)

Design Notes

• Compactness: Most W-shapes in ASTM A992 satisfy the compact limits in CSA S16 Table B4.1b for flexure (λ ≤ λp). This allows full plastic moment Mp development before local buckling occurs.
• Flange local buckling (FLB): The flange slenderness ratio bf/2tf is compared against λpf = 0.38√(E/Fy) ≈ 9.0 for compact sections.
• Web local buckling (WLB): h/tw is checked against λpw = 3.76√(E/Fy) ≈ 72 for flexure, and a more restrictive limit for uniform compression.
• Lateral-torsional buckling (LTB): Lp ≈ 432.9 cm (plastic limit). For unbraced lengths ≤ Lp, the full plastic moment is available. Between Lp and Lr, linear interpolation per CSA S16 Eq. F2-2 applies.

Verification (CSA S16): 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 — w360x287

Scenario: Hospital ward — strict deflection limits for medical equipment and services. Simply supported wide flange, 7.1 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 = 7087 mm (7.1 m)
• Total service load w = 14.7 kN/m
• Live load portion w_L = 6.3 kN/m
• Section w360x287: Ix = 999.0 × 10⁶ mm⁴, Sx = 5,080,000 mm³, Zx = 5,817,000 mm³
• Steel: fy = 350 MPa, E = 200,000 MPa
• Design moment resistance: φMn = 0.9 × Zx × fy = 1,832 kN·m

Step 1 — Live load deflection:

Δ_LL = 5 w_L L⁴ / (384 E Ix)

Δ_LL = 5 × 6.3 × (7087)⁴ / (384 × 200000 × 998,950,000)

Δ_LL = 1.0 mm

Step 2 — Deflection limit (L/360):

Δ_limit = L / 360 = 7087 / 360 = 19.7 mm

Step 3 — Dead + live deflection:

Δ_total = 2.4 mm

Step 4 — Design check:

✓ Live load deflection is within the L/360 limit.

Verify the design moment M*_Ed (from factored loads 1.35G + 1.5Q per CSA S16) does not exceed φMn = 1,832 kN·m. Also confirm shear resistance and bearing details at the supports.
