This camber table was adopted years ago when steel joists in flat roof systems experienced difficulties due to.
Open web steel jists roof.
When using open web steel joists pay attention to the joist camber next to adjacent framing and walls.
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 steel joist institute publishes in its specifications a camber table that is a requirement for steel joist manufacturing.
Since then this design solution for architects and engineers has evolved to support large floor areas and large roof spaces of up to and over 100 feet wide.
Steel joists joist girders.
In the late 1950 s redbuilt s founders invented an innovative composite steel and engineered wood open web truss.
Lh and dlh joists have heavier chords and web members for heavier loads and longer spans.
Open web steel joists are relatively light in weight fabricated in a shop setting and have a trussed web.
Open web steel joists are an engineered truss like construction component used to support loads over short and long spans alike.
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 structural frame i e.
Our joists and girders are engineered and manufactured in accordance with the specifications of the steel joist institute.
