Bulb Tee

Definition

A bulb tee is a rolled steel structural member in the form of a "T" with a formed bulb at the edge of the web.

Purpose

Bulb tees are used in construction for their high strength-to-weight ratio and ability to support significant loads. The bulb at the edge of the web provides additional stability and strength, making bulb tees ideal for applications such as bridge construction, flooring systems, and other load-bearing structures.

Examples of Use

1. Bridge Construction: Bulb tees are commonly used in the construction of bridge decks, providing a strong yet lightweight support structure.
2. Floor Systems: Used in the construction of composite floors where the bulb tee acts as a primary support element.
3. Roof Structures: In large buildings, bulb tees can be used to support roof panels, providing stability and strength.

Related Terms

• I-Beam: A steel beam with an "I" shape, commonly used in construction for similar purposes as a bulb tee.
• Structural Steel: Various steel shapes and forms used in building construction to provide support and strength.
• Girder: A large beam that supports smaller beams or joists in a structure.

Notes

The selection of bulb tees should be based on detailed structural analysis to ensure they meet the specific load and stability requirements of the project. Proper installation and alignment are crucial to maximizing their performance.
