Hinged, refers to connecting with a hinge. Commonly used in the connection of two parts of machines, vehicles, doors and windows, utensils, or parts, such as articulated trolleybuses, articulated trucks, and articulated passenger cars. Bearing connections, hinge connections, etc. are also common hinges. The common door leaf and door frame are connected together, so they cannot be separated, but they can still have some relative motion of conditions. This is mainly because the hinges that connect them give them the movement characteristics of the door leaf and frame. Later, people called the connection with the movement characteristics of the door leaf and the door frame as a hinge. Hinges are widely used in mechanical analysis and practical engineering. Below, Banjo Elbow Factory describes the pivoting capabilities of the articulation:

1. Rigid connection This structure assumes that the beam-column connection has sufficient rigidity, there is no relative rotation between the beam-column, and the connection can withstand bending moments. The structure of the hinged connection assumes that when the structure bears the gravity load, only the vertical shear force is transmitted between the main beam and the column, and no bending moment is transmitted. This connection allows for unrestricted rotation.

2. In the traditional analysis and design of steel structure frames, in order to simplify the analysis and design process, the beam-column connection is regarded as an ideal hinged connection or a complete rigid connection, and it is considered that the rotation constraint of the connection reaches more than 90% of the ideal rigid connection. , it can be regarded as a rigid connection; under the action of external force, the change of the angle between the axis of the column and the beam reaches more than 80% of the ideal hinged connection as a hinged connection. adopt rationale The assumption of hinged joints would mean that there would be no transfer of bending moments between beams and columns, and in terms of rotation, beams, and columns hinged together would rotate independently of each other.
