“…This paper uses a single element and elastic plastic hinge model with the proposed force recovery method to model the beam and the column. The computed ultimate load factor is 1.1 which is which is close to the result of [17]. From Figure 5 it can be seen that almost same collapse load is obtained by the total incremental iterative method with different load steps.…”

ABSTRACT:In this paper a total incremental iterative force recovery method suitable to plastic hinge analysis is proposed and it is found that this incremental iteration force recovery procedure has a convergence rate comparable to total secant method. The incremental force recovery manner makes this method be capable of recovering member internal forces and deformations correctly and conveniently in the existence of plastic hinge. The capability of the proposed total incremental iterative force recovery method to cope with plastic hinge is illustrated by two benchmark examples.

“…4 was analysed numerically in 1985 by Vogel [19], and this frame has been used by several researchers (e.g. Chan and Zhou [12] and Toma and Chen [20]) as a benchmark solution for including material non-linearities including residual stresses, gradual yielding and full-plasticity, as well as geometric non-linearities. Figure 4 shows the applied loading, material properties, member cross-section and geometry of the simple portal frame.…”

ABSTRACT:In the companion paper, a fourth-order element formulation in an updated Lagrangian formulation was presented to handle geometric non-linearities. The formulation of the present paper extends this to include material non-linearity by proposing a refined plastic hinge approach to analyse large steel framed structures with many members, for which contemporary algorithms based on the plastic zone approach can be problematic computationally. This concept is an advancement of conventional plastic hinge approaches, as the refined plastic hinge technique allows for gradual yielding, being recognized as distributed plasticity across the element section, a condition of full plasticity, as well as including strain hardening. It is founded on interaction yield surfaces specified analytically in terms of force resultants, and achieves accurate and rapid convergence for large frames for which geometric and material non-linearity are significant. The solutions are shown to be efficacious in terms of a balance of accuracy and computational expediency. In addition to the numerical efficiency, the present versatile approach is able to capture different kinds of material and geometric non-linearities on general applications of steel structures, and thereby it offers an efficacious and accurate means of assessing non-linear behaviour of the structures for engineering practice.

“…To overcome the inadequacy of analytical method, various numerical approaches based on finite element (FE) method have been proposed during the last two decades. In general, these methods may be categorized into two main types: the plastic zone method (spread-of-plasticity) [4][5][6][7][8][9][10][11][12][13][14][15][16][17] and the plastic hinge method (concentrated plasticity) [3,[18][19][20][21][22][23][24][25][26].…”
