The Steel Joist Institute (SJI) sizes and capacities from the 44th Edition Standard Specifications Load Tables and Weight Tables for Steel Joists and Joist Girders are now available in RISAFloor v12. There were no changes from the 43rd to the 44th Editions so you’ll see that these two are grouped together in RISAFloor. Prior versions of RISAFloor v12.0 include the steel joist values from the 42nd Edition Standard Specifications Load Tables and Weight Tables for Steel Joists and Joist Girders.
Staring in RISAFloor v12.0, there are now options for Steel Joist Databases which have different capacity values. The SJI Edition from which the values are determined is selected based on the Code specified on the Codes tab in the Model Settings.
