Diagram of a structure featuring plastic hinges. In the structural engineering beam theory, plastic hinge is the deformation of a section of a beam where plastic bending occurs. [1] In earthquake engineering plastic hinge is also a type of energy damping device allowing plastic rotation [deformation] of an otherwise rigid column connection. [2]
