The Floor Performance Tab

You can only enter floor performance information for a floor joist member. If you are sizing a member that is not a floor joist, the Floor Performance tab is disabled.

User Specified TJ-Pro™ Rating
Select the floor performance rating that you desire using any of the following options:

  • Minimum TJ-Pro Rating: Select the minimum value for your rating using a sliding scale. You can select a value in multiples of five.
  • Any TJ-Pro Rating: Check this box if you don't want to use TJ-Pro Rating as a design parameter. This value is calculated by ForteWEB software but will not be used to pass or fail a product.
  • User Defined: Enter the minimum value for your rating in the text box.

  • For more information on floor performance and the TJ-Pro Rating, see the Floor Performance Information topic within Help.  Additional information can be found on the Weyerhaeuser site here.

Note: Minimum TJ-Pro Rating and User Defined do not allow a value less than 20, or greater than 70. If your design TJ-Pro Rating results are below the minimum value you choose, the product will fail due to floor performance.
