Forces in an indeterminate truss

With surplus bars a statically determinate truss becomes internally statically indeterminate. In this case the truss is termed statically indeterminate. In an indeterminate truss, the bar forces depend on the elastic properties of the truss and cannot be calculated easily.

• investigation of bar forces in statically indeterminate trusses
• surplus bar, longitudinally adjustable
• straight and inclined loading possible
• load application device with force gauge mountable on different node disks
• measuring point to measure force on each bar
• measuring amplifier required
• software to evaluate measured values graphically
• storage system to house the components
• experimental setup in frame
