These are just a few of the many ways Forte visually makes the job easier.

With the latest Forte software, you can:

  • Define multiple member connections — choose to include fastener schedules along with the member design for attaching member plies of a beam assembly together. Select from a variety of nails, screws or bolts.
  • Specify the required building code year — select the building code required to design members. The building code, along with the year (e.g., IBC 2015), will be included on the member reports.
  • Design members for lateral loading using ASCE 7-10 — new building code options (IBC 2012 and IBC 2015) will now reference ASCE 7-10 for lateral design of members for stud, column and header applications. Choose IBC 2009 to use ASCE 7-05 for lateral design.
  • Increase productivity —quickly determine the best solution to use for a member now with additional information about which design accessories are required for each solution.
  • Integrate with Autodesk® Revit® — users’ modeling and design structures using Revit software will now have the ability to design Trus Joist® products using the MWF Advanced Revit extension from StrucSoft Solutions. Visit StrucSoft Solutions for more information.

Send members to Forte for analysis from your software

We provide the Forte File Format Utility to software developers looking to enhance their software so it exports floor, wall, and roof members to the Forte application for analysis. This allows your customers to skip remodeling spans, supports, and loads in Forte and instead send these calculations to Forte with all the necessary information pre-populated.

Learn more about this interactive guide for software developers wanting to transfer information into Forte files from their own software applications.
