Abstract

As the main torque sensor for real-time monitoring work, its development is of great significance to people. People use torque sensors to monitor and control torque in real time, which is critical to ensure the safe operation of the test system. This research is mainly to use the combined sensor method to measure the torsional vibration of the structure and analyze the anti-collapse performance of the shock-absorbing steel frame under strong earthquake. Experimental data shows that the limit bending moment of JD01 without end plate reinforcement is 130.7 kN•m, while the limit bending moment of end plate reinforcement is 160.7 kN•m. Compared with JD01, the bending ability of JD02 has increased by 22.95%. The results of the study show that the configuration of the reinforcing material of the bottom plate can effectively alleviate the stress concentration problem of the bottom plate, limit the surface deformation of the bottom plate, improve the rotation capacity of the node, and improve the support capacity of the node. The buckling restraint support can act as a reverse member of the elastic stage, supporting part of the horizontal shear force. The elastoplastic stage effectively adjusts the reverse side rigidity of the floor, adjusts the shear distribution of the floor, reduces the shear value of each layer, and finally delays the main bearing member to enter the elastic stage.
