The Steel Joist Institute (SJI) has developed a table that provides the approximate section properties for Virtual Joists for use by the Structural Engineer of Record (SER) in preparing the building structural models.
The intent is for the Virtual Joist tables to be used in the design models through use of the Member Selection and Code Check functions of the SER structural design software of choice. Using these functions, the structural design software treats the Virtual Joists as though they were custom wide-flange beams, and makes appropriate member selections, as well as displaying section properties and calculating approximate weights.
Virtual Joists are available for free download in Excel and Text format, along with a user guide. Complete the form or log in to your account to access this tool. SJI may notify you when updates are made to this design tool.
