Composite Steel Joists


Advantages of Steel Composite Joists
Benefits to be gained by using composite steel joists include the following:- Ability to route the new mechanical heating, ventilating, plumbing, and electrical lines through the joist open webs as shown in Figure 1. Customized web openings and configurations can be provided for large ducts.
- Ease of relocating and/or moving future HVAC during the life of the building.
- Better plenum space utilization.
- Floor-to-floor height can potentially be reduced by not having to run the mechanical lines under the joists. Also the more efficient and stiffer composite design makes it possible to support a given load with a shallower joist.
- Weight savings resulting from the efficient joist design reduces overall building costs.
- Simplified erection and connections provide for fastest construction.
- Large column free areas give the building tenant maximum flexibility when selecting a floor layout plan.
- Ability to provide customized composite joist designs for any given loading and serviceability requirements.
