A frame is a buckled or curved beam with rigid corners that forms a so-called clearance profile. Frames are used in various shapes and can be made of different materials, e.g. metal, wood or composite materials.
SE 200.09, in combination with other accessories of the MEC Line, enables the smart, digitally supported experimental setup for investigating frames made of stainless steel. The material properties are determined on a cantilever beam. A typical U-shaped frame, as used in hall construction, and an arched frame are available for the experiments. Statically indeterminate bearings can be analysed on both frame shapes. The load on the frame is applied via a vertical load SE 200.24 or the load unit SE 200.22. There are multiple load application points. Deformations can be recorded with one digital distance measurement, SE 200.23.
The theoretical analysis of deformation behaviour is based on energy-based approaches from the field of strength of materials. The starting point is the strain energy, which describes the internal energy stored in an elastically deformed frame. On this basis, the principle of virtual work enables a systematic derivation of the relationships between external forces and resulting displacements. Castigliano’s theorem allows the deformations at any point in the system to be determined directly from the strain energy. The combination of theoretical approach and experimental measurement enables a deep understanding of real structural behaviour. This allows the deformations and forces of overdetermined frames to be precisely predicted and experimentally verified.
The GUNT software identifies the components used and reacts dynamically to changes. The measured values are analysed in real time.
