Rotational Stability of Plastic Hinges
ce/papers, 2021AbstractThis paper is part of a larger project that considers the design of large steel‐framed warehouses and distribution centres (‘Big Sheds’) in the context of the SCOSS Alert “Effects of Scale” [1]. These buildings are currently designed to Standards and design procedures that were intended for much smaller structures, and are now long out of date.

A VARIATIONAL PRINCIPLE FOR PLASTIC HINGES IN A BEAM
Mathematical Models and Methods in Applied Sciences, 2009We focus on a variational model of an elastic–plastic beam which is clamped at both endpoints and subject to a transverse L∞ load: the mathematical formulation is a 1D free discontinuity problem with second-order energy dependent on gradient-jump integrals but not on the cardinality of gradient-discontinuity set.

Predicting behavior of plastic hinges subjected to large inelastic deformations caused by extreme loads such as earthquakes plays an important role in assessing maximum stable deformation capacities of framed concrete structures. This paper presents an analytical procedure that can be used to predict the behavior of plastic hinges in reinforced ...

Spread of Plasticity: Quasi‐Plastic‐Hinge Approach
Journal of Structural Engineering, 1994The paper describes a method of inelastic analysis for steel frames that provides the accuracy of distributed plasticity methods with the computational efficiency of elastic‐plastic‐hinge methods. It accounts for spread‐of‐plasticity effects without the need for through‐section and lengthwise discretization of a beam‐column element.

Plastic Hinging in Reinforced Concrete
Journal of the Structural Division, 1966The complete load-deflection history of 18 beams tested during 1952-54 and 18 beams tested during 1959-61 at the Univ. of Ill. allowed a study of the factors which contribute to ductility. All tests involved simple spans with load applied through a column stub at midspan to simulate the beam-column connection in a reinforced concrete frame.

Thermodynamics of plastic hinges with damage
Continuum Mechanics and Thermodynamics, 1991This nice study treats the embedding of the planar bending problem of an elastic bar with plastic hinges in equilibrium thermodynamics. At first, the balances of momentum, angular momentum and energy are stated, then the entropy balance is formulated and discussed after introducing a damage hypothesis.

1995
The plastic hinge concept was introduced in Chapter 1 when the “hinge-by-hinge” method was applied to solve the fixed-ended beam problems. In this chapter, we shall elaborate the concept of the plastic hinge and plastic moment. The methods of computing the plastic moment and the methods of using plastic moment in the design of a cross section will be ...

Plastic Shear Hinges in Steel Frames
Journal of Structural Engineering, 1983A mechanism for use in the limit analysis of steel frames where yielding arises in webs of members from couples of closely spaced forces is developed. This mechanism, called the shear hinge, is based upon the shear-moment interaction of the short portion of beam bounded by the couple.
