Hysteresis is a nonlinear phenomenon observed in the dynamic response behavior of numerous structural systems under high intensity cyclic or random loading, as well as in numerous mechanical and electromagnetic systems. For several decades, hysteretic response analysis of structural systems has been widely studied and numerous hysteresis models have been proposed and utilized in order to reproduce and better understand the complex hysteretically degrading behavior of structural systems. An important area of research in this regard has been the parameter identification of hysteretic systems. In this paper, we propose a modified Prandtl–Ishlinskii model to simulate the asymmetric hysteresis, which is the complex behavior in structural systems. In addition, a new approach based on particle swarm optimization and least-mean square algorithm is utilized for parameter identification of this hysteresis model. Finally, the model is applied in structural dynamic response analysis of a base isolated structural model under seismic load.

Abstract Any realistic model of structural wood systems must account for the equivalent hysteresis, which is the principal source of internal energy dissipation. Thus, determination of model parameters for hysteresis should be a first step in dynamic analysis. This paper presents a plan to use system identification techniques to estimate hysteresis model parameters for wood joints and structural systems from the extensive base of experimental data on cyclic tests that have been collected over the years around the world. A smoothly varying hysteresis loop, which represents an extension of the Bouc-Wen model, can be generated to bring about pinching as well as stiffness and strength degradation. The identified models will be used to study the dynamic response of single and multi-degree-of-freedom wood structures subjected to both deterministic and stochastic loads.
