The W40x249 is a W-shaped structural steel section identified by its depth-and-weight designation. This reference page presents the source dimensions, sectional area, unit weight, and related profile information for checking, detailing, and preliminary reference work.
Use the technical values below as the controlling local data for this page. For design decisions, verify material specifications, loading, connection requirements, stability, and applicable project criteria with the responsible engineer.
W Beam
refer to : AISC 16
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.
Depth : 1000.8 mm
Width : 401.3 mm
Web Thickness : 19 mm
Flange Thickness : 36.1 mm
Root Fillet Radius : 30 mm
Sectional Area : 474.19 cm2
Unit Weight : 372.2 kg/m
W40x249 section reference
The profile data describes the section’s overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight. These properties serve different purposes: dimensions support layout and detailing, sectional area supports mass and some strength-related calculations, and unit weight supports estimating and handling considerations.
Reading the profile dimensions
The web and flanges form the primary visible parts of a W beam. The web connects the flanges, while the flange thickness and width affect connection detailing, clearances, and the way the section is represented in drawings. The root fillet is the transition region between the web and flange and should be considered where fit-up or connection geometry approaches that area.
Using the AISC reference
The source identifies AISC 360-16 as the applicable AISC specification reference. That specification addresses the design, fabrication, and erection of steel structures in the United States. A section listing is a reference aid, not a complete design check; member selection and detailing still require project-specific engineering review.
CAD and drafting workflow
The downloadable DWG can support drawing preparation, layout coordination, and section-shape reference. Confirm units, scale, insertion settings, and the drawing’s geometric orientation before incorporating the file into a project model. Related resources on W shapes, section properties, steel connections, and CAD details can help place this profile in a broader design workflow.
Frequently asked questions
What type of steel section is W40x249?
W40x249 is a W beam, commonly described as a wide-flange structural steel section. The page identifies its geometry and mass-related properties for reference and detailing.
What information is provided for W40x249?
The source content provides overall depth, overall width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
What does the AISC 360-16 reference indicate?
It identifies the AISC Specification for Structural Steel Buildings, 2016 edition, as the referenced specification for structural steel design, fabrication, and erection in the United States.
Can the DWG be used directly for structural design?
The DWG is a drafting and geometric reference resource. It does not replace engineering checks for member strength, stability, connections, fabrication, or project-specific requirements.
Should the listed properties be verified before use?
Yes. Treat the local source values as the page reference, then confirm the required section data, material information, units, and project criteria before using them in calculations or issued drawings.
