The Gerber beam is an articulated beam with several supports that is often used in bridge construction. The lines of influence are determined to take account of moving loads in the design. Lines of influence describe static reactions to a moving load, e.g. internal reactions of the beam or support reactions.
SE 200.07, in combination with other accessories from the MEC Line, enables the smart, digitally supported experimental setup of a Gerber beam. The experiment contains a Gerber beam consisting of two cantilevers, each with a smart support and an inserted suspended beam. Supports and loads are available as smart accessories. The experimental arrangement is set up in the SE 200 mounting frame. The stainless steel mounting frame provides direct and wireless data transmission and power supply for the smart components. The click system ensures the components easily snap into place.
Each cantilever has two support positions and a holder for the support. The suspended beam is mounted on both support arms of the cantilevers in articulated bearings. The roadway can be loaded at 13 positions with individual loads or line loads, as well as in the centre with a vertical load. In experiments, the forces on the bearings, supports and the loads are measured and displayed as a measured value both directly on the smart components and in the GUNT software. The lines of influence are determined by measuring a moving load. The exact position of the loads on the roadway is detected using a binary code (Gray code).
The GUNT software identifies the position and location of the applied loads and reacts dynamically to changes. The visualisation in the software corresponds to the actual Gerber beam. The measured values are analysed in real time.
