The W14x34 steel beam reference below provides the listed geometric dimensions and mass information for this W-shape designation. Use these values as a drafting and reference aid, while relying on the governing project specifications and a qualified structural engineer for design decisions.
The source data identifies the applicable AISC reference and includes a downloadable DWG file. For related guidance, see the site’s references on W-shape dimensions, steel section properties, and steel connection detailing.
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 : 355.6 mm
Width : 171.4 mm
Web Thickness : 7.2 mm
Flange Thickness : 11.6 mm
Root Fillet Radius : 10.2 mm
Sectional Area : 64.52 cm2
Unit Weight : 50.6 kg/m
How to use this W14x34 reference
The dimension entries describe the overall shape and its primary material thicknesses. Depth and width help establish the section envelope for drawings and coordination. Web and flange thicknesses describe the principal plate elements, while the root fillet radius identifies the curved transition where the web and flange meet.
The listed sectional area and unit weight serve different reference purposes. Sectional area describes the amount of steel in the cross-section; unit weight describes the member’s mass per unit length. Neither value, by itself, establishes a beam’s allowable capacity, serviceability performance, connection resistance, or suitability for a particular structure.
Drafting and detailing considerations
When preparing layouts, connection details, or fabrication information, account for the root fillet rather than assuming a sharp web-to-flange corner. The supplied DWG can support CAD coordination, but the downloaded geometry should be checked against the project’s required reference, detailing conventions, and revision controls before it is used for fabrication or construction documents.
For design-oriented work, pair this dimensional reference with the site’s material-grade information, section-property references, and steel connection design guidance. A licensed structural engineer should verify all design assumptions and final member selections.
Frequently asked questions
What does the W14x34 designation identify?
It is the identifying designation for this W-shape entry. Use the complete designation consistently in drawings, specifications, schedules, and CAD files so the intended section is clear.
Can the listed dimensions be used to select a beam for a project?
The dimensions are useful for coordination and preliminary reference, but they do not establish structural capacity. Final selection requires project-specific evaluation of loads, span, restraint, stability, connections, materials, applicable requirements, and serviceability.
What is the purpose of the root fillet radius?
The root fillet is the curved transition between the web and flange. It affects how adjacent connection plates, fittings, weld access, and detailing clearances are arranged, so it should not be treated as a sharp inside corner.
What is the DWG download used for?
The DWG is intended to assist CAD and drafting workflows. Confirm its geometry and revision against the authoritative project reference before using it for fabrication or construction documentation.
