Steel truss design

In Tekla Structural Designer although truss members can be defined in any material, design is restricted to steel trusses only.

Design is performed using a set of design forces obtained from 3D Analysis. (Grillage Chasedown Analysis and FE Chasedown Analysis results are not required.)

Truss members can either be defined manually, or the process can be automated using the Truss Wizard. Irrespective of the method used the resulting truss members will be one of four types:

  • Internal
  • Side
  • Bottom
  • Top
Depending on the type, different design procedures are adopted:
  • Internal and Side Truss Members are designed as steel braces (for axial forces only).

    see: Steel brace design

  • Top and Bottom Truss Members are designed as steel beams, with the exception that seismic forces are not considered.
