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 W8x18 reference
The dimensional fields describe the overall depth and width of the section, together with web thickness, flange thickness, and the root fillet radius. These dimensions help engineers and detailers coordinate framing layouts, check clearances, and compare related W-shape entries.
The sectional area and unit weight provide section-identification data for estimating material quantities and coordinating drawings. They should not be treated as a complete design check. Strength, stability, connection behavior, serviceability, material grade, and applicable project requirements must be evaluated separately.
Reference and CAD workflow
This entry identifies the AISC Specification for Structural Steel Buildings (AISC 360-16) as its reference. Consult the original project requirements and the applicable design documentation when using the data for engineering work.
The downloadable DWG can support drafting and coordination workflows. Before issuing drawings, verify the imported geometry, units, layer conventions, orientation, and any project-specific detailing requirements. Related internal references may include W-shape section properties, steel terminology, connection detailing, and other AISC shape resources.
Frequently asked questions
What type of section is W8x18?
It is identified in the source as a W beam, also commonly described as a wide-flange steel section.
What information is provided for W8x18?
The entry provides dimensional properties, sectional area, unit weight, an AISC reference, and a DWG download for drafting use.
Can the listed values be used as a complete structural design?
No. The values support section identification and reference work, but design requires project-specific checks for loads, stability, connections, material requirements, and applicable codes.
What should be checked before using the DWG file?
Confirm the drawing units, geometry, scale, orientation, layers, and compatibility with the project drafting standard before incorporating the file into production documents.
