SJI Virtual Joists Available

The Steel Joist Institute (SJI) previously developed Virtual Joist tables to estimate the section properties for Open Web Steel Joists. These Virtual Joist sections are characterized as equivalent wide-flange beams which closely approximate the joist chord area, effective moment of inertia, and weight. Virtual Joists are also available in the RFEM and RSTAB cross-section database.

The sections can be found under Rolled Cross-Sections - I-Sections and by further selecting "SJI" from the Manufacturer/Standard group. Both the Virtual Joist (VJ) and Virtual Joist Girder (VJG) tables are available here.

Virtual Joists and Virtual Joist Girders in Cross-Section Database

The Virtual Joist sections can be utilized like any other member in RFEM/RSTAB. After an analysis is run, member results such as the internal forces, stresses, deflections, and so on, can be viewed along the member length.

The ability to optimize the sections based on SJI joist design tables is currently not possible. The optimization process will be added in the future for RFEM 6.
