[0002] In construction projects, the usage status of the steel bar structure in beam-columns is crucial, and they play a key role in ensuring the structural safety, load-bearing capacity and durability of buildings.

[0003] The steel bar structure in beam-columns is mainly used to enhance the load-bearing capacity and tensile strength of concrete. Since the tensile strength of concrete itself is relatively low, the addition of steel bars (17, see Figure 1 ) can significantly improve the bending resistance, shear resistance and tensile strength of beam-columns.

[0004] The steel bar structure can also improve the deformation performance of concrete, reduce the crack width, and improve the integrity and durability of the structure. The installation of the steel bar structure should follow the construction specifications and design requirements to ensure the accurate position, spacing and quantity of the steel bars. During the installation process, measures should be taken to prevent the displacement and deformation of the steel bars.

[0005] The existing tests for the strength of the beam-column steel bar pouring structure generally use a single impact test device, which has a single impact range and cannot perform local supplementary tests; moreover, without the assistance of a directional guide rail, the impact direction and angle are not unified, and the test accuracy is insufficient, which needs to be improved.
