Final answer:
In engineered floor systems, the component that has the same depth as I-joists is called a rim board. Rim boards provide additional support to the I-joists and help distribute the load evenly across the floor system.
Step-by-step explanation:
In engineered floor systems, there is a component used that has the same depth as I-joists. This component is called a rim board. A rim board is a horizontal member that is placed on top of the I-joists and acts as a load-bearing element.
In engineered floor systems, the component that has the same depth as I-joists is called a rim board. Rim boards provide additional support to the I-joists and help distribute the load evenly across the floor system.
Rim boards are typically made of wood or engineered wood products like oriented strand board (OSB) or laminated veneer lumber (LVL). They provide additional support to the I-joists, helping distribute the load evenly across the floor system. For example, if you have a floor system using 14-inch deep I-joists, you would use a 14-inch deep rim board.
