Web

Definition

A Web is the vertical plate connecting the top and bottom flanges of a beam.

Purpose

The purpose of the web is to transfer shear forces between the top and bottom flanges of a beam, contributing to the overall structural integrity and load-bearing capacity of the beam.

Examples of Use

• Steel I-Beams: The web connects the flanges and supports the loads in structural steel beams used in construction.
• Bridge Girders: Girders with webs are essential in bridge construction for supporting spans and distributing loads.
• Building Frameworks: Used in the construction of multistory buildings to support floors and roofs.

Related Terms

• Flange: The horizontal top and bottom parts of a beam that provide resistance to bending.
• Shear Force: A force that acts perpendicular to the length of a beam, causing it to shear.
• Girder: A large beam that supports other beams in a structure.

Notes

The web's thickness and material properties are critical in determining the beam's capacity to handle shear forces and overall stability.
