Series overview

W16 series

The W16 series groups AISC W-family shapes that share the same nominal-depth designation prefix. Weights and actual depths still vary within the series, so use the table below to compare candidates before analysis.

The AISC W16 series contains 11 published sections ranging from 26.00 to 100.00 lb/ft . Actual depths range from 15.70 to 17.00 inches, despite the shared W16 nominal designation .

Questions & answers

W16 FAQs

What is the W16 series?

It is the set of published AISC W shapes whose designation begins with W16. Members share a nominal-depth label but can differ in weight, actual depth and properties.

Why do actual depths differ within W16?

The number in the designation is nominal. Published overall depth varies by weight. Always use the tabulated depth for clearance and detailing.

How should I choose among W16 weights?

Compare weight, Ix, Sx, flange geometry and project constraints, then analyze finalists under the same span and loads. There is no universal “best” section.

Can I analyze a W16 section in Optimal Beam?

Yes. Select a designation above and choose Analyze to load its properties into the beam calculator.
