How to read the W18x86 reference
The source identifies this member as a W beam and lists its principal geometric and weight-related properties. The reported dimensions describe the overall section and its main components: depth, flange width, web thickness, flange thickness, and root fillet radius.
What the listed properties describe
- Depth and width: The overall section dimensions used to identify the beam’s envelope in drawings and reference layouts.
- Web and flange thickness: The thicknesses of the central web and projecting flanges, which are important when reviewing detailing, connection clearances, and fabrication information.
- Root fillet radius: The curved transition between the web and flange. This detail matters when interpreting accurate shape geometry rather than treating the section as a collection of sharp rectangular plates.
- Sectional area: The cross-sectional area reported for the complete steel shape.
- Unit weight: The mass per unit length reported in the source data. Use the stated unit system consistently when preparing material estimates or coordinating drawings.
Using the DWG reference
The downloadable DWG can support CAD reference and preliminary detailing workflows. Confirm the drawing units, layer conventions, project requirements, and any fabrication or connection details before incorporating the file into a construction document set.
Geometric reference data does not by itself establish a member’s design capacity or suitability for a particular structure. Design checks, material requirements, connection design, stability considerations, and project-specific loading remain the responsibility of the qualified design professional.
W18x86 FAQ
What is the W18x86?
W18x86 is the designation used for this W-shape steel beam entry. The source provides its dimensions, section area, unit weight, and related geometric properties.
Which standard is referenced for this section?
The entry refers to the American Institute of Steel Construction Specification for Structural Steel Buildings, identified in the source as AISC 360-16 and its 2016 edition.
What do the web and flange dimensions represent?
The web dimension describes the thickness of the central portion of the shape, while the flange dimension describes the thickness of the top and bottom projecting portions. The source also reports the flange width and root fillet radius.
Is a CAD file available for W18x86?
Yes. The source includes a downloadable DWG reference for the W18x86 entry. Review units and project drafting requirements before using it in design documentation.
Can the listed properties be used as a complete design check?
No. The listed values are reference data for identifying and documenting the section. A complete design evaluation requires project-specific engineering checks and verification by a qualified professional.
