Origins and development of 3D-BASIS (3-Dimensional BASe Isolated Structures) was initially envisioned by the need for an efficient tool for nonlinear dynamic analysis of three-dimensional base isolated structures, particularly in solving the highly nonlinear bidirectional stick-slip hysteretic response of a collection of sliding isolation bearings and the resulting response of the superstructur...

Hysteresis is a nonlinear phenomenon present in many structures, such as those assembled by bolted joints. Despite large number of recent findings related to identification techniques for these systems, the problem still challenging and open contributions. To fill gap concerning proposition algorithms based on closed-form solutions, this work introduces use harmonic balance method identify stoc...

In this paper, several variants of Differential Evolution, Particle Swarm Optimization and Genetic Algorithms are employed for the identification of a BoucWen hysteretic system that represents a full-scale bolted-welded steel connection. The purpose of this work is to assess their comparative performance in a highly nonlinear identification problem. Interesting results are produced that reveal ...

In this paper, a moving-average method of smoothing noise based on complex exponential decomposition is applied to eliminate non-stationary signal and non-linear produced by Bouc–Wen model, which are added white Gaussian simulate the in measured signal. The uses sliding window cutting entire and/or into small segments considers that stable linear. decomposed series components via decomposition,...

Nonlinear state-space modelling is a very powerful black-box approach. However powerful, the resulting models tend to be complex, described by large number of parameters. In many cases interpretability preferred over complexity, making too complex unfit or undesired. this work, complexity such reduced retrieving more structured, parsimonious model from data, without exploiting physical knowledg...

Piezo-actuated stage (P-AS) has become the topic of considerable interest in realm micro/nanopositioning technology recent years owing to its advantages, such as high positioning accuracy, response speed, and large output force. However, rate-dependent (RD) hysteresis, which is an inherent nonlinear property piezoelectric materials, considerably restricts application P-AS. In this research pape...

In the area of semi-active control of civil structures, Magneto-Rheological (MR) damper has been an efficient mechanism for reducing the seismic response of structures. In this paper, an effective method based on defining an optimization problem for designing MR dampers has been proposed. In the proposed method, the parameters of semi-active control system are determined so that the maximum res...

This research paper represents the analysis and simulation of semi-active suspension using non-linear modeling Magneto-Rheological (MR) with consideration hysteresis behavior for a quarter car model. The is based on assumption that each wheel experiences same disturbance excitation. Hysteresis analyzed Bingham, Dahl's, Bouc-Wen models. focuses passive, Dahl, models five road profiles. desired d...
