The W10x77 is a wide-flange structural steel beam reference used for dimension checking, section identification, estimating, and drafting coordination. This page presents the local AISC 16 data for the shape together with a downloadable DWG file.
Use the dimensional information as a reference for layout and detailing, not as a substitute for project-specific engineering. Material specification, resistance checks, connection design, stability, loading, and applicable project requirements must be verified by the responsible engineer.

the American Institute of Steel Construction (AISC) Specification for Structural Steel Buildings (AISC 360-16), which is the 2016 edition of the AISC Specification for Structural Steel Buildings. It provides guidelines and requirements for the design, fabrication, and erection of steel structures in the United States.

How to use this W10x77 reference
The source data identifies the overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight. Together, these values help engineers and detailers coordinate member geometry, check clearances, prepare drawings, and compare the section with other W shapes.
The listed sectional area and unit weight support quantity takeoffs and general reference work. They should be used consistently with the project’s material, fabrication, corrosion-protection, and estimating assumptions. For structural design, confirm the governing specification, load effects, limit states, unbraced conditions, connection details, and any local amendments rather than relying on the shape label alone.
Geometry and detailing considerations
Web and flange thicknesses affect how the member interfaces with plates, bolts, welds, stiffeners, and framing components. The root fillet is also relevant when a connection or bearing detail approaches the rolled section profile. Shop drawings and connection details should account for the actual rolled geometry shown in the applicable reference data.
For broader terminology, compare this entry with the site’s structural steel shapes, section properties, and steel connection detailing references. The accompanying DWG can support CAD coordination, but the drawing should be checked against the project’s modeling standards and the governing design documents before issue.
W10x77 frequently asked questions
What does W10x77 identify?
It identifies a W-shape structural steel beam designation. The source table on this page provides the corresponding geometry, sectional area, and unit weight for reference.
What is the W10x77 used for?
It can be referenced during steel member selection, preliminary layout, quantity estimation, and drafting coordination. Final use in a structure requires project-specific engineering verification.
Why are web, flange, and fillet dimensions important?
These dimensions define the rolled profile and influence fit-up, clearances, bearing details, stiffener layout, and connection detailing. They should be considered when developing fabrication and erection drawings.
Is the downloadable DWG ready for construction?
The DWG is a CAD reference resource. Review its geometry, units, layer conventions, and project coordination requirements before incorporating it into construction documents.
Which specification is referenced on this page?
The source content refers to the AISC Specification for Structural Steel Buildings, AISC 360-16. Confirm the specification and project requirements applicable to the work being designed.
