Definition
An open-web steel joist is a prefabricated, welded steel truss used at closely spaced intervals to support floor or roof decking.
Purpose
Open-web steel joists provide strong and lightweight structural support for floors and roofs, allowing for longer spans and more open interior spaces without the need for intermediate supports.
Examples of Use
- Commercial Buildings: Used in warehouses and retail stores for supporting roofs and floors.
- Industrial Structures: Providing structural support in factories and manufacturing plants.
- Residential Construction: Occasionally used in larger residential buildings to support floors and roofs.
Related Terms
- Truss: A framework of beams forming a rigid structure.
- Beam: A structural element that primarily resists loads applied laterally to the beam's axis.
- Decking: The material used to cover the floor or roof structure.
Notes
- Strength-to-Weight Ratio: Offers an excellent strength-to-weight ratio, making them ideal for large spans.
- Installation: Prefabrication allows for quicker installation compared to traditional joists.
