How to use this shape information
The sectional area and unit weight support material takeoff and preliminary comparison work, while the geometric dimensions help with drafting and constructability reviews. They do not, by themselves, establish a member’s available strength or allowable use in a particular structure. Design checks should use the governing project criteria and the applicable steel design provisions.
AISC reference and CAD file
The source identifies AISC 360-16, the American Institute of Steel Construction specification for structural steel buildings. The page also provides a DWG download for the W40x183. A CAD file can assist with drawing production, but its geometry should be checked against the project’s approved reference data before fabrication or construction documents are issued.
Related reference topics include steel section properties, W-shape terminology, steel connections and detailing, and structural steel CAD resources.
