In an I-beam, which element connects the top and bottom flanges?

Explanation:
The web is the piece that connects the top and bottom flanges in an I-beam. The flanges are the horizontal shelves that handle bending, while the vertical web links the two flanges and carries shear forces between them. This arrangement lets the flanges resist bending moments while the web ties the flanges together, keeping the beam as one unit under load. The flange material itself isn’t the connector between flanges, and a diagonal brace isn’t part of a standard I-beam’s geometry, which is why the web best fits as the connecting element.
