MEC - Three-hinged arch

Three-hinged arches are commonly used in bridge construction. A three-hinged arch consists of a curved beam that is mounted on two fixed bearings and usually contains the crown hinge at the crown. The system is statically determinate due to the crown hinge.

• measurement of the support forces of a three-hinged arch under different loading
• three partial arches for setting up a symmetrical or asymmetrical three-hinged arch or a beam, clamped on one end
• one partial arch fitted with electronic module for measuring the forces with direct display
• calculation and display of the bending moment in the software
• setup of the entire experiment arrangement in the mounting frame
• click system for simple, fast experimental setup without cabling
• loading of the three-hinged arch with optional individual loads (including as moving load), line load, vertical load
• automatic identification and exact position detection of the loads on the roadway by means of a binary code (Gray code)
• display of the measured values and visual representation of the forces in the software
• software via USB under Windows 11
• digital multimedia teaching material online: E–Learning course, worksheets
