ready assembled Warren truss

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.
