Open Web Steel Joists

Trusses are perhaps the most recognizable of all structural forms. They are elegant and evocative. They span over rivers and lakes in our bridges and they grace the roofs of the buildings in which we congregate and assemble.

There are two main forms of trusses; flat trusses are used to support low-slope roofs, floors, and bridge decks while vaulted trusses are used to support steep-slope roofs as with wood roof trusses in modern houses. Open web steel joists (OWSJ) are the standardized, work-horse version of flat trusses. They typically have parallel or near-parallel chords with webs forming a pattern of evenly spaced triangles.

Design & Customization

The layout, span, depth, and loads for OWSJ are typically specified by the structural engineer of record (SEoR) for a building project. Many times there are further requirements for OWSJ specified by the SEoR such as requiring panel points at certain locations along the truss span, requiring top chord extensions at truss end(s), or requiring that bottom chords extend to connect to the supporting wall or column. All of these requirements can be accommodated in our OWSJ designs.
