“虚拟托梁”(VJ) 和“虚拟托梁”(VJG) 表格都位于各自类别的标准化截面下（图 1）。
The Virtual Joist sections can be utilized like any other member in RFEM and 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.
