In steel engineering, what is called rigid connection? What is articulated? What kind of nodes or structural parts are applicable to the two? The more detailed the answer, the better!
Steel structure, beam to column connections are usually used in 3 forms, flexible connection (also known as articulated) and semi rigid connection and rigid connection. In engineering practice, how to distinguish a node belonging to the rigid and semi rigid or hinged connection depends on the rotational stiffness, rigid connection should not have obvious connection with the angle of angle deformation, reduce deformation of the structural resistance should not exceed 5%.
To connect by means of hinges. A device or part commonly used in two parts of a machine, vehicle, door, window, and implement, such as articulated trolley buses, articulated freight cars, articulated buses.
Rigid connection refers to the connection between two members of a rigid joint.In steel structures, for example, the I-beam is rigidly connected, which means that the two flanges are connected to the flange and the web, while the hinge is just the web connection. The flange is not connected.
