Truss beam: Warren girder (SE130.01)

Truss beam: Warren girder (SE130.01)

ready assembled Warren truss

CodeSE130.01

Description:

  • 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.
