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]
Plastic Bending Stress Distribution. Plastic bending [1] is a nonlinear behavior particular to members made of ductile materials that frequently achieve much greater ultimate bending strength than indicated by a linear elastic bending analysis. In both the plastic and elastic bending analyses of a straight beam, it is assumed that the strain ...
Further increment in load does not increase the moment at the points where the plastic hinges are formed. The increased load increases the moment in the less stressed sections of the beam; hence due to this, further plastic hinges are formed. This process of shift of application of moment in the beam is termed as moment redistribution in a beam ...
In reinforced concrete structures, the damage state variable quantifies the crack density in the plastic hinge zone; [1] in unreinforced concrete components and steel beams, it is a dimensionless measure of the crack surface; [2] in tubular steel elements, the damage variable measures the degree of local buckling [3] The LDM evolution laws can ...
In structural engineering, the plastic moment (M p) is a property of a structural section. It is defined as the moment at which the entire cross section has reached its yield stress . This is theoretically the maximum bending moment that the section can resist – when this point is reached a plastic hinge is formed and any load beyond this ...
A man who tortured a man for two days before he jumped to his death from a 12th-storey flat has been jailed for eight years. Lee Smith, 37, abducted Jamie Forbes, also 37, and held him against his ...
It is typically thinned or cut to allow the rigid pieces to bend along the line of the hinge. The minimal friction and very little wear in such a hinge makes it useful in the design of microelectromechanical systems, and the low cost and ease of manufacturing makes them quite common in clamshell containers and other disposable, recyclable ...
The Tesla Cybertruck explosion and fire at the entrance of the Trump Hotel in Las Vegas Wednesday morning is being investigated as a possible terrorist act, according to a law enforcement official ...
