Can I use FreeCAD for creating and testing roof truss ? If not, are there any software in Linux that I can use to do so ?

In Windows, I've use SAP2000 for testing and analyzing the truss that I've created, but in Linux I haven't found software that can do the same. There is Frame3DD, but it's too hard for me to use, especially because the lack of GUI.
