[0002] In structural engineering experiment, the response of the structure as a whole or the component under various loads or actions is usually studied by using a physical model, which is one of the important means of studying the mechanical properties of structures. The structure as a whole or the component needs to be connected together through a connecting device and an experimental machine. The tension experiment of the structural component is generally divided into two types: axial tension and eccentric tension. Firstly, the axial tension experiment generally connects the component and the tension testing machine together through bolts or welding. Secondly, the eccentric tension experiment is used to simulate the working condition of the component under the action of tension and bending moment coupling. This kind of experiment is generally realized by setting the eccentricity between the axis of the component and the tension machine. In the actual experiment of the eccentric tension of the structural component, the component itself will produce axial elongation and bending under the action of tension and bending moment, so the tension is generally applied through a rotating hinge support.
