Family overview

What are AISC HSS Rectangular?

AISC rectangular HSS are closed hollow structural sections used for frames, beams and columns where a rectangular tube is preferred. Designations list outside height × width × nominal thickness. Published design thickness is smaller than nominal and is used for design properties. This hub filters the finder to rectangular HSS for comparison, charts and calculator handoff.

Designations

Understanding HSS Rectangular designations

HSS6×4×3/8

Rectangular HSS designations list outside height × width × nominal wall thickness, such as HSS6×4×3/8. Use design thickness for property-based calculations unless the specification says otherwise.

tw (Design) Design wall thickness in, mm Reduced wall thickness used for published design properties
A Cross-sectional area in², mm² Total steel cross-sectional area
Ix Moment of inertia (x) in⁴, mm⁴ Major-axis flexural stiffness
Iy Moment of inertia (y) in⁴, mm⁴ Minor-axis flexural stiffness
Sx Elastic section modulus (x) in³, mm³ Elastic bending property about the x-axis
Sy Elastic section modulus (y) in³, mm³ Elastic bending property about the y-axis
Zx Plastic section modulus (x) in³, mm³ Plastic bending property about the x-axis
Zy Plastic section modulus (y) in³, mm³ Plastic bending property about the y-axis
rx Radius of gyration (x) in, mm Strong-axis radius of gyration
ry Radius of gyration (y) in, mm Weak-axis radius of gyration and lateral stability relevance
J Torsional constant in⁴, mm⁴ Torsional constant

Selection

How to compare HSS Rectangular

  • Match outside height and width to architectural or connection envelopes.
  • Compare nominal versus design thickness before using properties.
  • Review Ix and Iy for the governing bending axis.
  • Compare square HSS when equal sides are preferred.

Questions & answers

HSS Rectangular FAQs

How are rectangular HSS designated?

They list outside height × width × nominal thickness, for example HSS6×4×3/8.

What is HSS design thickness?

Design thickness is smaller than nominal wall thickness and is the thickness used for published design properties.

When choose rectangular versus square HSS?

Choose rectangular when the two outside dimensions differ to suit depth or width constraints; choose square when equal sides are preferred.

Can I analyze rectangular HSS in Optimal Beam?

Yes. Select the section and choose Analyze.
