During the test, according to the pre-set parameters, the impact tester releases the drop hammer or pushes the impact device, and the drop hammer falls freely at a certain height, applying an impact load to the concrete component. The size and method of the impact load can simulate different impact scenarios. During the impact test, it is necessary to record the response of the concrete component, including data such as impact force, deformation, and crack expansion. By analyzing the test data, the performance of the concrete component under impact load can be evaluated, including its failure form, impact resistance, etc. These results are of great significance for engineering design, safety assessment of building structures, etc.
