How to read the W33x354 reference
The source content identifies this member as a W beam and reports its overall depth, flange width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These properties describe the physical section and provide a starting point for section identification, estimating, drafting, and engineering review.
Dimensions and detailing considerations
Depth and width help establish the member envelope for layout and coordination. Web and flange thicknesses are useful when reviewing connection geometry, fabrication details, copes, penetrations, and clearances. The root fillet radius is especially relevant where plates, angles, seats, or other connection components must fit against the rolled profile.
Sectional area and unit weight
Sectional area is a geometric property commonly used with material and design calculations, while unit weight expresses the member’s mass per unit length. Neither value, by itself, establishes a member’s capacity. A complete engineering check may also require section-property data, material specifications, load effects, connection design, stability checks, and the governing project requirements.
AISC reference and CAD workflow
The listed reference is the AISC Specification for Structural Steel Buildings (AISC 360-16). Treat the dimensions and properties on this page as the authoritative local reference for this entry, and confirm project-specific requirements before design or fabrication. The linked DWG file can support drawing setup and coordination; review the downloaded geometry against the source data before using it in issued documents.
Frequently asked questions
What type of steel section is W33x354?
It is identified in the source content as a W beam, also called a wide-flange structural steel section.
What information is provided for W33x354?
The entry provides the section dimensions, root fillet radius, sectional area, unit weight, an AISC 360-16 reference, and a DWG download.
Can these dimensions alone be used to select the member for a project?
No. Member selection requires an engineering review of loads, material, span and support conditions, stability, connections, applicable design requirements, and the complete set of relevant section properties.
Why is the root fillet radius important?
The root fillet can affect the fit and detailing of components placed near the web-to-flange transition, including connection plates and other attachment elements.
What is the DWG file used for?
The DWG file is intended as a CAD reference for drafting and coordination. Verify its geometry and units before incorporating it into project drawings.
