SE 130.01 Truss Beam: Warren Girder Show data sheet (pdf file) Print page
Technical Description

Warren truss beams are frequently used on steel constructions.
  Experiments with the truss SE 130.01 are mounted on the frame of the SE 130 unit. 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 discs is "hinged". So this can be described as an ideal truss.
  The force in the bars is measured using strain gauges. Owing to the symmetrical construction, only half of the bars have strain gauges on them. All strain gauge connections are housed together in the strain gauge box.

 

Learning Objectives / Experiments

- Calculation of tensile and compressive forces in bars in different load

  cases: straight and inclined forces
- Comparison of measurement results with mathematical methods
