The term Open Web Steel Joists K-Series as used herein refers to open web parallel chord load-carrying members suitable for the direct support of floors and roof decks in build-ings utilizing hot-rolled or cold-formed steel including cold-formed steel whose yield.

The Composite Joist or CJ-Series system is an open web system where the concrete slab acts as the composite top chord of the underlying steel joists. Shear transfer from the concrete slab to the underlying steel joists is accomplished by welding steel shear. One type of structural failure is chord plastification where a thin steel web within the truss punches through the wall of the supporting cord of the truss eventually leading to instability or structural failure.

Moreover the frame pieces of open web trusses are hollow and connected only by welded steel cords. Open-webbed steel joists are usually used in a commercial steel-framed building to support.

Steel joists and Joist Girders being erected. In structural engineering the open web steel joist OWSJ is a lightweight steel truss consisting in the standard form of parallel chords and a triangulated web system proportioned to span between bearing points. The main function of an OWSJ is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to the.

Metal web joists allow easier installation of services such as plumbing cabling heating pipes etc. Resulting in the reduction or elimination of surface pip. Joists are a great way to frame a roof and can also be successfully used to frame a floor generally on a shorter 2-3 stories building.

Joists are generally cheaper than their WF counterparts since they end up using less steel. The trade-off is joist depth and as others have mentioned less availability of changing buildings program. The indicated spans are based on simple span joists.

Minimum end bearing length is 1½ spans in bold require web stiffeners at OSB end panel. Maximum spans are measured centerline to centerline of bearing and are based on uniformly loaded joists. Total Load deflection is limited to L240.

Live Load deflection is limited to L480. As with all metal web joist applications the open web nature means any services for lighting can be hidden within the joists void keeping ceiling lines neat and tidy. Pitched roof joists are becoming increasingly popular for projects where solid timber cannot span the desired length without the need for expensive additional supports.

An open-webbed truss is cost-effective. An open-web truss design works out to be more cost-effective than a UB rafter design because both steel and hot-dip galvanising are purchased at a per tonne rate. A UB rafter being heavier than a web truss means you will spend money more on the steel and the galvanising process for your shed if you opt.
