Today, open web steel joists are one of the most commonly used framing systems for floors and roofs in buildings. Some of the first steel joists used in the United States in the mid to late 1800s were made of sheet steel webs and flanges riveted together.
Learn how to determine who the original manufacturer was and whether they can provide any additional documentation. Learn how to verify the original design loads and evaluate the joist for the new loads. Discuss procedures, as part of the evaluation, to identify the joist components and connections that are inadequate.
