Technical Field
[0001] The utility model relates to the technical field of earthquake test benches, in particular to a support for an earthquake test bench. Background Art
[0002] Seismic test benches play a crucial role in research on the seismic resistance and damping of building structures. They can reproduce earthquake environments according to test requirements and expectations. They also convert the structural model's response under the shaking table into the structure's actual seismic response through data processing and theoretical analysis. This not only provides a clear understanding of the structure's macroscopic seismic performance and the damage mechanism under earthquakes, but also accurately identifies vulnerable areas. The development of shaking tables has significantly advanced research into seismic resistance and damping devices for building structures.

However, there are some shortcomings in the existing ones. For example, the bracket has a fixed shape, which is not suitable for operating test benches of different heights. In addition, the bracket is large in size and is often transported by forklift, but it is difficult to fix it, so it needs to be improved. Utility Model Content
