Truss beam: Warren girder (SE130.01)

Truss beam: Warren girder (SE130.01)

ready assembled Warren truss



  • Warren truss beams are frequently used on steel constructions.
  • Experiments with the truss SE 130.01are mounted on the frame of the SE 130
  • The mechanical construction of the truss ensures that only tensile or compressive forces are active in the bars.
  • The connection between the bars by means of node disks is “hinged”.
  • So this can be described as an ideal truss.
  • The force in the bars is measured using strain gauge measurement.
  • Owing to the symmetrical construction, only half of the bars have measuring points on them.
  • All strain gauge connections are housed together in the strain gauge box.

Technical details:


  1. investigation of bar forces in a single plane, statically determinate truss
  2. ready assembled Warren truss beam
  3. influence of dead-weight minimised by horizontal experiment layout
  4. any straight and inclined load cases possible
  5. pre-balanced strain gauge connection box
  6. SE 130.01is a supplementary set for the main unit SE 130
