“…For the displacement fields representing a plate with a free edge (Eqs. (4), (6) and (9)), each displacement component consists of a trigonometric series in the x-direction in the same manner as in Ovesy, Loughlan and GhannadPour [18], and a linear variation in y-direction.…”

“…For example, Reznikov [194] develops a method for the analysis of the nonlinear deformation of composites including finite rotations. Ovesy et al [183] perform the nonlinear CSA of channel sections using the so called finite strip method. An innovative procedure for the precise CSA of stresses is given by the asymptotic variational methods which take advantage of certain small parameters inherent to beam-like structures [248].…”

Nowadays, the use of energy dissipating devices to improve the seismic response of RC structures constitutes a mature branch of the innovative procedures in earthquake engineering. However, even though the benefits derived from this technique are well known and widely accepted, the numerical methods for the simulation of the nonlinear seismic response of RC structures with passive control devices is a field in which new developments are continuously preformed both in computational mechanics and earthquake engineering. In this work, a state of the art of the advanced models for the numerical simulation of the nonlinear dynamic response of RC structures with passive energy dissipating devices subjected to seismic loading is made. The most commonly used passive energy dissipating devices are described, together with their dissipative mechanisms as well as with the numerical procedures used in modeling RC structures provided with such devices. The most important approaches for the formulation of beam models for RC structures are reviewed, with emphasis on the theory and numerics of formulations that consider both geometric and constitutive sources on nonlinearity. In the same manner, a more complete treatment is given to the constitutive nonlinearity in the context of fiber-like approaches including the corresponding cross sectional analysis. Special attention is paid to the use of damage indices able of estimating the remaining load carrying capacity of structures after a seismic action. Finally, nonlinear constitutive and geometric formulations for RC beam elements are examined, together with energy dissipating devices formulated as simpler beams with adequate constitutive laws. Numerical examples allow to illustrate the capacities of the presented formulations.

“…The theoretical developments are mostly based on semi-energy method. Ovesy et al [12][13][14] have developed a Semi-energy post-local-buckling FSM (S-e FSM) in which the out-of-plane displacement of the finite strip is the only displacement which is postulated by a deflected form as distinct to that mentioned previously with respect to the semi-analytical FSM (S-a FSM) and Spline FSM. The developed semi-energy FSM (S-e FSM) has been applied to analyze the post-local-buckling behaviour of thin flat plates [12], open channel-section [13] and box section struts [14].…”
