Spandrel Beam

Definition

A spandrel beam is a beam that runs along the outside edge of a floor or roof.

The purpose of a spandrel beam is to provide structural support along the perimeter of a building, distributing loads from the floors and roof to the vertical columns or walls.

Examples of Use

• High-rise buildings use spandrel beams to support the outer edges of each floor, transferring loads to the vertical columns.
• In bridges, spandrel beams support the deck and transfer loads to the supporting piers or abutments.
